Titanium ingot to ASTM B977/B977M in CP Grade 1 / 2 / 3 / 4, aerospace Grade 5 (Ti-6Al-4V) and ELI Grade 23 (Ti-6Al-4V ELI). VAR single, double (EBM + VAR) or triple melt routing per AMS 2380, 5-60 kg weight class at Ø150-600 mm. Sourced against upstream Baoji melting campaigns with EN 10204 3.1 certification and heat-level traceability; MOQ and schedule are quotation-specific.
Honest Positioning
BOZE Metal is a sourcing and processing partner for titanium ingot, not a primary melter. Ingot is sourced from upstream Baoji melting campaigns. The following scope clarifications are necessary for accurate technical and commercial alignment before any melting route is committed.
Sponge chlorination, Kroll reduction, VAR / EB furnace operation and ingot pouring are not inside our vertically integrated scope. We source ingot from upstream melters; our scope is grade and route review, ingot geometry agreement, inspection coordination, documentation and shipment.
General Grade 5 ingot supply is not automatic aerospace approval. Approved material specifications, approved process sources, customer source restrictions and downstream forging qualification remain separate controls unless explicitly written into the order.
We supply material to medical material specifications (ASTM F67, F136) where applicable. We are a material supplier and processor, not a finished medical device manufacturer; downstream device-level certification remains the device maker responsibility.
Minimum order quantity and schedule depend on grade, melting route, weight class, alloy availability and the current upstream furnace campaign. Treat them as quotation-specific values confirmed during engineering review.
Titanium sponge is the raw melt feedstock, not a finished product. If your requirement is sponge rather than cast ingot, that is a different supply chain and is outside our current scope — raise it at RFQ so we can decline or redirect honestly.
A single-melt order cannot be silently upgraded, downgraded or substituted to a triple-melt route to meet a delivery date. Any route change requires written agreement and becomes part of the revised order basis.
Buying Essentials
Ingot price is dominated by melting route and campaign size, not by alloy name alone. Four variables decide the quotation — state all four before comparing offers.
VAR single melt, double melt (EBM + VAR) or triple VAR melt, per AMS 2380. The number of remelts is the largest cost and purity driver in the order.
Ingot weight per piece, diameter, height, cylindrical or rectangular section, and the as-cast, skin-machined or pickled surface condition.
Forging, extrusion, rolling or re-melt route, and the downstream specification the ingot must satisfy (for example ASTM B348 billet or AMS 4928 forging stock).
Melt-route records, full chemistry, oxygen and interstitial limits, heat-level traceability, EN 10204 3.1 certificate and any third-party witnessing.

Form Selection
Ingot, billet, slab and sponge are frequently conflated in enquiry traffic. The controlled purchase description is the exact grade, standard, melting route, weight class, diameter, surface condition and quantity.
The as-cast melting product itself — the direct charge for a forging, extrusion or re-melt route. State the melting route, weight class and diameter explicitly.
The forged or reduced intermediate product derived from ingot. For billet, rod and bar geometry downstream of the forge, use the dedicated bar and rod page.
Large cross-section flat stock produced by rolling. For plate and sheet geometry downstream of the slab, use the dedicated plate and sheet page.
The chlorination-grade porous titanium feed used to melt an ingot. Sponge is a raw melt feedstock, not a finished product, and is outside our supply scope.
Processing Options
Preparation for the forging, extrusion or re-melt route can be reviewed against grade, melting route, ingot geometry, surface requirement, tolerance and quantity.
Before requesting a quotation: identify the ingot weight class, the downstream forging or extrusion press opening, and whether the route requires as-cast, skin-machined or pickled surface. The preparation method and achievable tolerance remain order-specific.
Vacuum arc remelting is the standard refining route for titanium ingot. Each additional VAR pass removes gas, oxide and volatile contamination, which is why triple-melt routes are specified where the lowest inclusion level is required. CP Grade 1 / 2 / 3 / 4, Grade 5 (Ti-6Al-4V) and Grade 23 (Ti-6Al-4V ELI) ingot is reviewed against the melt count your downstream process requires.
Each ingot lot is released against a heat or lot reference carried through melting, casting, inspection and shipment. Marking, document set, protective packing and delivery basis are checked before release, so the certificate, the ingot and the forging route downstream can be reconciled against one order basis.
Process Review
Melting is executed against the upstream campaign; melting route, ingot geometry, preparation, inspection scope and documentation are confirmed by quotation against the approved order basis.
Grade, specification revision, melting route, ingot weight, diameter, quantity and document scope are aligned before any melting campaign is scheduled.
The single / double / triple VAR route, ingot weight class and furnace campaign are confirmed against the accepted quotation basis before the melt is scheduled.
Melting, pouring and cooling are executed to the agreed route. Ingot weight, diameter and surface condition are controlled within the scope stated in the order.
Chemistry, ingot geometry and surface are inspected to the agreed level. Furnace-run and heat records are retained against the ingot for traceability.
Heat marking, document set, protective packing and the delivery basis are checked before the ingot lot is released for shipment.
Supply Scope & Qualification
A certificate name alone does not define the complete acceptance package. State the traceability level, inspection characteristics, melt-route records, marking, third-party involvement and release documents required by the order.
Grade, heat or lot reference, product form, ingot weight and certificate link recorded for each released ingot lot.
Melting route, number of VAR passes, furnace-run data and full specification chemistry reported for the agreed heats.
Ingot diameter, weight, height and surface condition, with the inspection method, sampling level and report format agreed per order.
Required document index, language, approval route and delivery timing confirmed before production. Release documents follow the order basis.
Before You Order
Use this short check before comparing quotations. The complete guide covers supplier evidence, acceptance, commercial scope and change control.
Grade, ingot form, specification revision, melting route and heat or lot basis.
Weight class, diameter, surface condition, ingot count and the downstream forging or re-melt route.
Chemistry basis, melting records, inspection level, hold points and acceptance criteria.
Quantity basis, exclusions, protective packing, Incoterm and the schedule assumption behind the quoted date.
Supply Chain
Four supply-side controls that determine whether a specific ingot order can be accepted, and on what schedule.
Melting capacity is scheduled against upstream Baoji VAR furnace campaigns rather than a captive plant. Engineering sample quantities and full heat quantities are both reviewable; campaign timing is confirmed at the RFQ stage.
There is no blanket minimum order quantity for engineering sampling. Full heats, triple-melt routes and specific alloy campaigns are scheduled against upstream furnace batches; the accepted MOQ is stated in the quotation.
Lead time is driven by the melting campaign, the specified melt route and current alloy availability. Standard and non-standard routes are quoted as specific values at the RFQ stage rather than as a fixed schedule.
Triple-melt routes and specific alloy campaigns require dedicated furnace time. Feasibility, campaign timing and the accepted route are confirmed before an order is accepted.
Material Comparison
Five procurement-relevant dimensions comparing titanium ingot against the conventional non-ferrous melt-feedstock alternatives, in terms of melting route cost, inclusion control and downstream process fit.
| Dimension | Titanium Ingot (CP Gr.2 ref.) | Aluminium Ingot | Copper Cathode / Billet |
|---|---|---|---|
| Density | 4.51 g/cm³ — lowest of the three, highest strength per unit mass | 2.70 g/cm³ — requires larger sections for equal stiffness | 8.96 g/cm³ — heavy, low strength per unit mass |
| Inclusivity and fracture control | Tight inclusion control via multi-pass VAR; well suited to fatigue-critical forgings | Widely used where stiffness governs; different inclusion profile | High conductivity and thermal expansion make fatigue design different |
| Corrosion behaviour | Passive film, resistant to seawater, chloride and oxidising media | Excellent oxide film; susceptible to chloride pitting when unalloyed | Susceptible to acidic and ammonia-bearing environments |
| Melting route sensitivity | VAR must be repeated for the highest-purity aerospace routes; route is a real cost driver | Secondary remelt sufficient for most structural applications | Oxygen pickup is a common control concern rather than a purity driver |
| Downstream process fit | Forge, extrude and roll at reduced temperature; strict control of forging ratio | Conventional forging and rolling window; broad process tolerance | Hot working window is narrow; high thermal mass affects tool load |
