UNS C64200 Aluminum Silicon Bronze Fasteners
UNS C64200 Aluminum Silicon Bronze Sample MTC Certificate
Access a comprehensive, professionally formatted Material Test Certificate according to EN 10204-2004: 3.1 for UNS C64200 (Aluminum Silicon Bronze) fasteners. Review the documentation verifying its high-strength hot-forging chemistry, superior corrosion resistance, and mechanical performance.
What's Inside This C64200 MTC Certificate
This sample mill test certificate details the critical chemical and mechanical parameters for UNS C64200 fasteners. Known as Aluminum Silicon Bronze, this alloy is designed for heavy-duty structural applications where high yield strength, excellent hot forgeability, and resistance to environmental stress cracking are absolutely essential.
- Full Traceability: Certified with TC No.: S412/26-XX and fully mapped to ASTM F468 and ASTM B150 specifications for high-strength nonferrous bolting.
- Aluminum-Silicon Chemistry: Explicitly verifies the complex chemistry: Copper base with ~7% Aluminum (Al) and ~2% Silicon (Si). This addition is what provides the alloy with its high structural strength, excellent hot-forging properties, and resistance to wear.
- Extreme Structural Strength: C64200 is characterized by its high yield strength (often exceeding 350 MPa in forged tempers), making it an ideal choice for critical fasteners in heavy mechanical and structural assemblies.
- Corrosion & Wear Resistance: The alloy forms a robust, protective oxide layer that makes it highly resistant to atmospheric, marine, and industrial corrosion, while its inherent toughness prevents premature wear.
- Quality Compliance: 100% visual inspection and precision dimensional checks executed to ASME B18.2.1 standards. Material is characterized by being non-magnetic and highly resistant to galling.

Technical FAQs — UNS C64200 Aluminum Silicon Bronze MTC
Why is C64200 (Aluminum Silicon Bronze) unique?
UNS C64200 is a "hot-forgeable" alloy, meaning it remains workable at high temperatures, allowing it to be formed into complex, high-strength fastener heads. Unlike many other copper alloys, its mechanical strength actually approaches that of steel, making it the perfect bridge between copper's corrosion resistance and steel's structural load-bearing capability.
How does C64200 compare to C63000 (Nickel Aluminum Bronze)?
While both contain Aluminum, C63000 adds Nickel for extreme saltwater corrosion resistance. C64200 replaces that Nickel with Silicon. The Silicon gives C64200 better hot-forgeability and higher tensile strength compared to C63000. Essentially, C64200 is chosen when high mechanical strength and forging complexity are needed, while C63000 is chosen for the absolute highest levels of saltwater corrosion resistance.
Is C64200 magnetic?
No. UNS C64200 is entirely non-magnetic. Because of this, it is frequently used in applications where magnetic interference must be avoided—such as in high-precision scientific instruments, offshore underwater sensor housing fasteners, and specialized electrical equipment.
