Custom Tin Bronze Industrial Parts – Process & Quality Assurance Statement
Our custom tin bronze industrial parts are engineered for demanding applications that involve high loads, sliding wear, and challenging service conditions where durability is essential.

Key process features

Production combines traditional casting with precision machining to deliver consistent quality and exact specifications:
●Alloy Preparation: High-grade virgin ingots and returns are melted with precise tin additions to achieve the target composition.
●Melting & Degassing: Induction melting with fluxing and degassing removes impurities and gases for clean metal.
●Casting Method: Centrifugal or sand casting produces dense blanks with minimal shrinkage defects.
●Rough Machining: CNC turning and milling establish basic geometry with allowances for final finishing.
●Heat Treatment: Optional stress-relief annealing improves machinability and stability.
●Precision Machining: High-accuracy operations achieve exact dimensions, threads, grooves, or complex features per your drawings.
●Final Cleaning & Packaging: Parts are thoroughly cleaned and individually protected to arrive ready for assembly.

Quality control system

● Complete traceability from raw material charge to finished part
● Material certificates and dimensional reports provided with each order
● Sample retention ≥3 years for third-party verification (SGS, BV, TÜV, etc.)
● 100% inspection of critical parameters:
• Chemical composition (optical emission spectrometry)
• Mechanical properties (compression, hardness, and tensile testing on samples)
• Dimensional accuracy (CMM and gauges; typical tolerance ±0.05mm on key features)
• Surface finish and defects (profilometer and visual checks)
• Internal soundness (ultrasonic testing on critical sections)
● Internal standards meet or exceed ASTM B505 requirements. Typical C90500 properties:
Compressive strength >800 MPa, Excellent resistance to pounding and wear, Proven performance in high-pressure bearing applications.
● ISO 9001:2015 certified manufacturing ensures every custom tin bronze industrial part delivers the strength, wear resistance, and precision your heavy-duty projects require.
