Product Description

copper-aluminium bimetal clad strip

Clad metals are two distinct metals or alloys that are metallurgically bonded together so that the optimum combination of functional properties is achieved. Copper Aluminium offers the inherent
characteristics of aluminum while the copper cladding provides greater conduction of current and
 the ease of soldering copper.

1.  Material:
Copper T2, Aluminum 1series, 3series, 8series etc.

2. Cast-rolling process:
Solid-Liquid machining processing technique to bond copper and aluminum in oxygen-free environment permanently and firmly.

3. Application:
3.1 Electric power industry (conductive industry)
3.2 Decoration industry
3.3 Shipping industry
3.4 Stamp & sea

4.Cu Al bimetal strip
