Heat treatment and self-control components of Bimetallic Wear Resistant Material
Oct 17, 2018

Bimetallic Wear Resistant Material are composite materials. They are mainly metal semi-solid forming technologies when used. The recent industrialization focuses on: aluminum-steel, titanium-steel, copper-steel, aluminum-titanium, copper-aluminum and other bimetals. material. Due to the performance of heterogeneous composites, low cost and wide range of applications, the development potential of traditional materials has increased.


Bimetallic Wear Resistant Material, hole saws, hand saws, jigsaws, reciprocating saws and other products are also produced by two different metal materials, namely "backing material" and "tooth material" by electron beam welding, heat treatment and other processes. Another example is the copper-clad aluminum bimetal wire, which applies the skin effect of current. The surface of the wire is copper with good electrical conductivity, which satisfies the need of wire conductivity. The middle of the cross section is aluminum, which greatly reduces the cost of the wire.


Bimetallic Wear Resistant Material simple self-control element that can realize its temperature control. It is a material for making hot bimetal. Its hot bimetal is a relatively simple self-control element for temperature control. It consists of two layers of metals (or alloys) with different coefficients of thermal expansion. A layer with a large expansion coefficient is an active layer, and a layer with a small coefficient of thermal expansion is called a passive layer. When the hot bimetal is heated, the length of the active layer freely expands is greater than that of the passive layer, but since the two layers are firmly bonded together, the hot bimetal is bent into an arc shape. The opposite is true when cooling. This feature allows the manufacture of thermal relays. Commonly used for overload protection of electric motors.
