Frequently Asked Questions

Get answers to common inquiries about our products and services.

Is tin-coated copper wire safe?

Yes, tin-coated copper wire is safe and widely used in electronics and electrical applications. The tin coating enhances solderability, prevents oxidation, and creates stronger, more reliable electrical connections, reducing the risk of short circuits.

What is tungsten wire used for?

Tungsten wire is used in applications requiring high melting points and strength, such as incandescent light bulb filaments, vacuum furnace heating elements, welding electrodes, and aerospace components.

Why is tungsten not used as a general-purpose wire?

While tungsten has excellent high-temperature strength, it is brittle at room temperature, difficult to draw into fine wires, and more expensive than copper or aluminum. Thus, it's reserved for specialized high-heat applications.

Can I get custom wire specifications?

Yes, we offer custom wire manufacturing for diameter, length, alloy composition, and packaging. Contact us with your requirements for a tailored solution.

Do you export worldwide?

Yes, we export our tinned copper, tin-copper alloy, and tungsten wires globally, serving industries in electronics, automotive, telecommunications, and renewable energy.
