METAL PARTS-battery packs
Metal parts Forms
Supplied in thicknesses from 0.03mm to 6mm, our copper strips are available for immediate supply on an ex-stock basis. Copper strip is a malleable product which benefits from high thermal and electrical conductivity. Heat dissipation in copper is superior to other alloys, including aluminium. Copper strips offer high tensile strength combined with excellent corrosion resistance and benefits from a high degree of dimensional stability. Copper is also non-sparking and non-magnetic. Predominantly, the product finds extensive use in the global electronics sector.
Overview
In recent years, the lithium battery industry has developed rapidly, and the market has higher and higher requirements for lithium battery life and fast charging performance.
