FAQ — Titanium CNC Machining, Compliance & Quality Assurance

Yes, absolutely. BOZE operates a fully locked-down aerospace material control network. Every single batch of titanium alloy we procure for defense and aerospace contracts strictly complies with DFARS 252.225-7014 Clause 1 (Preference for Domestic Specialty Metals) and its relevant supplements. All raw material stock is sourced exclusively from tier-one, NADCAP-accredited mills located in DFARS-approved qualifying countries.

Each delivery is anchored by an authentic, unedited EN 10204 Type 3.1 Material Test Report (MTR), charting complete chemical ladle analysis and mechanical destructive testing metrics. Our internal digital inventory ledger executes absolute heat number traceability, linking the raw bar stock to the precise mill melt lot, matching the physical parts throughout the entire multi-axis CNC processing lifecycle.

To eliminate the risk of catastrophic field failure caused by internal micro-voids or low-density inclusions (LDIs), BOZE enforces a rigorous multi-tiered non-destructive testing infrastructure. We execute Ultrasonic Testing (UT) strictly in compliance with ASTM A388 or AMS 2154 Class A acceptance criteria, employing multi-channel immersion transceivers to isolate internal material discontinuities down to equivalent flatted hole boundaries of ≤ ∅0.8 mm.

Furthermore, for critical structural dynamic interfaces, we mandate Liquid Penetrant Testing (LPT) per ASTM E1417 / E1417M standards to detect surface-breaking microscopic fractures. All NDT evaluations are conducted by certified ASNT Level II / Level III technicians, providing comprehensive, audit-ready validation logs for high-reliability components.

Hydrogen embrittlement represents a critical threat to the structural ductility of titanium under sustained stress. BOZE completely mitigates this risk by restricting chemical exposure parameters and enforcing rigid thermal processing control per AMS 2801. Our thermal stress relief cycles are executed exclusively inside high-vacuum furnace chambers running atmospheric zones at a minimum vacuum threshold of 10⁻⁴ Torr, maintaining soak temperatures precisely between 480°C and 540°C to fully release residual processing alignment stresses without inducing grain boundary distortion.

When chemical etching or pickling is mandatory, we utilize tightly calibrated nitric-hydrofluoric acid solutions where the HNO₃ concentration is continuously maintained at a minimum 10:1 ratio relative to HF, effectively blocking nascent hydrogen migration into the alpha-beta crystal matrix.
