Benefits of Etching Copper

No burrs ,pressure points and gaps

No burrs ,pressure points and gaps .The thickness of copper is 0.03mm ,0.04mm and 0.05mm are widely used in VCM spring production .

Stable structure and properties

The copper parts are not easy to deformed and the surfaces are free of oxidation

Excellent Elasticity

The high nickel and tin-containing copper alloy materials have excellent elasticity exceeding that of beryllium bronze and can be used as the base belt of composite strips
