WM4857 Tungsten Copper Bar

Tungsten Copper Bar Description

Tungsten Copper Bar is a pseudo-alloy of copper and tungsten. As copper and tungsten are not mutually soluble, the material is composed of distinct particles of one metal dispersed in a matrix of the other one. The alloy combines the properties of both metals, resulting in a material that is heat-resistant, ablation-resistant, high thermal and electrical conductivity, and easy to machine.

FAQs

Q1 Why is Tungsten Copper used for thermal management?
Tungsten Copper bars are excellent for thermal management due to their high thermal conductivity. Copper provides efficient heat dissipation, while the high density of tungsten ensures that the material can withstand high temperatures and harsh environments, making it ideal for heat sinks and thermal management devices in electronics and industrial applications.

Q2 What is the cost of Tungsten Copper Bars?
The cost of Tungsten Copper bars can vary depending on factors such as:

• Composition: The ratio of tungsten to copper can influence the material's cost.
• Purity: Higher purity materials may cost more.
• Size and shape: Custom sizes and shapes may lead to higher manufacturing costs.
• Quantity: Bulk orders can often reduce the cost per unit. For accurate pricing, it’s recommended to request a quote based on specific needs and quantities.

Q3 Can Tungsten Copper Bars be machined?
Yes, Tungsten Copper bars can be machined using standard machining techniques, including milling, turning, and drilling. However, due to the hardness of tungsten, special care and tools may be required during machining to ensure precision and avoid excessive wear on equipment.
