T2 Flat Tinned Copper Bar for High Current Conductivity Copper Bar 4mm Thick Width 40mm Length 1000mm

Thickness: 4 mm/0.157 inches, Width: 40 mm/1.575 inches, Length: 1000 mm/39.37 inches. Material: Tinned copper (copper purity ≥ 99.9%), T2 copper; Shape: flat bar. Power copper bars have the advantages of low resistivity, high bending ability and corrosion resistance. This product is tinned to improve corrosion resistance and electrical conductivity, reduce resistance and prevent patina. Copper is easily oxidized and blackened in the atmosphere, producing a patina that affects electrical contact. Metal tin is very stable in the atmosphere and has very good conductivity, so tinning can solve the problem of copper instability in the atmosphere. Package: 1 x Flat Bar
