Technical characteristics

Chromium Copper is a copper alloy containing 0.6 to 1.2% Cr. The main operational advantage of this alloy — high strength, corrosion resistance and good conductivity. Chromium copper can be subject to aging at elevated temperatures when the chromium precipitates from solid solution. Strength chromium copper is almost two times higher than that of pure copper, high electrical conductivity (it is 85% if compared to pure copper).

Strength

These high strength alloys retain their strength at elevated temperatures. The corrosion resistance of the alloys based on chromium better than pure copper because chromium improves the chemical properties of the protective oxide film. Chromium copper possesses excellent cryogenic stability and a good deformability at elevated temperatures.

Use

The manufacture of such parts as electrodes for resistance welding, switch gears, cable connectors, parts of circuit breakers, mould, manufacturing of spot welding tips, and electrical and thermal conductors that require increased strength.

Classification

According to the standards of ASME copper-chromium alloys are designated as C18050… C18600 and cast alloys — as C81400… C81540. The chemical composition of the alloys according to the technical requirements of ASTM F9, includes 99% of copper and at least 1% chromium.
