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: Featuring an impressive tensile strength range of 620-900 MPa and a yield strength of 450-750 MPa, altering slightly by temper, this copper alloy is built to withstand tough conditions.
High Conductivity: Showcasing an outstanding electrical conductivity of 25-34 MS/m, translating to 45-60% IACS, surpasses standard bronze and brass in performance.
Stress Relaxation Resistance: Even at elevated temperatures of 200°C, it retains over 70% of its residual stress, proving its reliability in high-stress applications.
Formability: Exhibits excellent cold workability, with a minimal bending radius of merely 2 times the thickness, facilitating diverse fabrication needs.
Eco-Certified: Proudly lead-free and entirely compliant with RoHS and ELV standards, aligning with modern eco-friendly initiatives.
