Properties of Products

 

 When the product is at “M” status, should be followed the standard GB/T1234-1995

1) Resistivity:

 

 

 

2) If the diameter of wire is less than 1.00mm resistance per meter, the products should be followed the  standard GB/T1234/1995

3) At any position of each spindle, the resistance uniformity can’t be allowed to excess 4%.

4) Mechanical properties

The wires witch diameter is 0.50-6.00mm, after winding five rings, doesn’t appear stratification and crack
