DongYang's brand
'Copper-Lite' was developed in 1985. Its supply is not only restricted
to the domestic market, but broadly exported to various overseas countries.
|
| Characteristics |
| |
|
Outstanding formability...Copper
material itself acts as excellent lubricant, thus processing is
very easy and successful.
Excellent
cohesiveness... Since the melting point of copper
is significantly lower than the average melting point of general
steel, it contributes to the better melting cohesiveness as a
charicteristic.
Superior
weldability...Its
outstanding ability to weld makes electrolytic copper plated steel
an excellent metal in numerous industries.
