Notes
note_altCuBe2: The Peak of Copper Alloy Engineering
When engineering requirements reach the absolute limit of mechanical stress, CuBe2 (C17200) is the definitive solution. At Çorum Bronz, we provide this specialized beryllium copper alloy for industries that require a material with the strength of steel and the unique properties of copper.
Strength Comparable to Steel
The defining characteristic of CuBe2 is its ability to reach a hardness of up to 45 HRC after heat treatment. This makes it indispensable for heavy-duty bushings and high-stress mechanical parts. Unlike steel, however, CuBe2 is completely non-magnetic and non-sparking, making it the primary material for safety tools used in explosive atmospheres and components for sensitive medical or military electronics.
Performance in Extreme Conditions
Fatigue Life: CuBe2 is famous for its "memory" and resilience, making it the gold standard for springs and diaphragms that must operate millions of times without losing their shape.
Thermal Management: While slightly lower in conductivity than CuCo2Be, it still offers far superior heat dissipation compared to steel, preventing localized overheating in high-friction environments.
Wear Protection: Its natural lubricity and resistance to galling ensure that moving parts last longer, even in the absence of consistent lubrication.
Çorum Bronz supplies CuBe2 in compliance with strict international standards (including ASTM B196 and DIN 17666). Whether you need rods, strips, or custom-forged parts, our quality assurance ensures that your most critical components are backed by world-class metallurgy.
