American Tungsten (ANSI/ASTM144-733)
American tungsten is an alloy of tungsten, copper and other elements. This alloy is used in a variety of applications including electrical contacts, non-sparking tools, and other components where high hardness and wear resistance are needed. Typically, American tungsten is composed of over 90% tungsten along with various mixtures of copper and other elements. This combination of the
three elements creates a material with excellent wear and abrasion resistance, high hardness, and great electrical and thermal conductivity.
When converted into its pure form, tungsten is a very dense, hard and brittle metal. In addition, it has a high melting point and an excellent electrical conductivity. Copper on the other hand has a low melting point, excellent electrical and thermal conductivity, and corrosion resistance. These two metals create a combined material that has a high density, excellent hardness and wear resistance, as well as excellent electrical and thermal conductivity. The additional elements in American tungsten help to improve the overall strength and performance of the material.
The most common use of American tungsten is for electrical contacts. This type of contact is used in a wide variety of electrical devices, such as switches, connectors, and circuit breakers. The hardness of American tungsten makes it ideal for electrical contacts that see a lot of wear and tear, as the material is able to resist the wear and tear of repeated use.
Additionally, American tungsten is commonly used in machined components, as it has high wear and abrasion resistance. The combination of tungsten and copper also gives American tungsten excellent electrical conductivity. This makes it a great choice for components that will be exposed to harsh working conditions, as it will provide superior operation even in extreme temperatures.
American tungsten is also useful for manufacturing non-sparking tools, such as those used for mining operations. This type of tool is designed to minimize the risk of sparks and fires in hazardous environments, by limiting the contact of metal to metal parts. By utilizing tungsten and copper in a non-sparking tool, these hazards are minimized and the user can rest assured knowing that the job being completed is done safely.
Due to its high resistance to wear and tear, American tungsten is also used for components that are frequently exposed to corrosive chemicals. The alloy’s protective coating helps prevents these components from corroding, so they can be used continuously without experiencing any damage.
American tungsten is a great choice for applications that require high-performance materials, as the combination of tungsten and copper ensures a long lasting, durable material. Its excellent hardness and wear-resistance, combined with its electrical and thermal conductivity make it a great choice for a wide variety of applications.
