Product Description

Product Details for CuNi3Si1Mg (C70250)

1. Core Specifications
Item Details
Grade CuNi3Si1Mg (UNS C70250)
Standard ASTM B888, RoHS & ELV Compliant
Composition Cu (Balance), Ni 3%, Si 0.65%, Mg 0.15%, Pb <0.05%
Material Type Precipitation-Hardened High Copper Alloy
2. Key Advantages

High Strength: Impressive tensile strength ranging from 620 to 900 MPa and yield strength of 450 to 750 MPa, depending on the temper. This gives the material robust power and endurance.
High Conductivity: Outstanding electrical conductivity between 25 to 34 MS/m, translating to 45-60% IACS, surpassing the usual bronze or brass standards.
Stress Relaxation Resistance: Remarkable ability to maintain over 70% residual stress even at elevated temperatures of 200°C.
Formability: The product boasts exceptional cold workability, with a minimum bending radius of 2× the thickness, providing flexibility in design.
Eco-Certified: Proudly lead-free and compliant with global standards like RoHS and ELV, ensuring environmentally friendly practices.

3. Typical Applications
Industry Applications
