1. Introduction
The copper-based low resistance heating alloy is widely used in low-voltage circuit breaker, thermal overload relay, and other low-voltage electrical product. It is one of the key materials of the low-voltage electrical products. The materials produced by our company have the characteristics of good resistance consistency and superior stability. We can supply all kinds of round wire, flat and sheet materials.
Each spool/package of alloy is supplied with a label or tag showing alloy type, nominal size, tare and net weight, resistance W/m (W/ft), charge number and a reference number.
wires:0.018-10mm                   Ribbons:0.05*0.2-2.0*6.0mm
Strips:0.5*5.0-5.0*250mm       Bars:D10-100mm

Do you provide free samples?
Yes, we can provide a free sample for testing, If we have sample in stock, The quantity based on the material type, The buyer should bear all the shipping costs.

Please feel free to send us a inquiry and we are looking forward to cooperating with you!

Q:Windows7 how to connect the TV operation (how to set up the computer)?
As the bird's feet are his step on the same high-voltage wire, the distance between the birds and the feet determine the voltage. The distance between the feet of the birds is very small, so the voltage is very small, the equivalent of 0. Do not let the birds electric shock.
