Product Description

ASTM TM19 Thermal bimetal strip

Generally, hot rolling, cold rolling and hot pressing methods are used for composite, and alloy with low melting point can also be cast onto solid metal layer with high melting point for composite.
The composite method depends on the properties of constituent metals and the application conditions of bimetals.
The high expansion coefficient layer in the bimetallic belt is called the active layer, mainly including iron-nickel-chromium, iron-nickel-manganese, manganese-nickel-copper alloy, etc; The low expansion coefficient layer is called the passive layer, mainly including iron-nickel alloy.

Main features: Linear temperature range is higher, low thermal performance, can be used at high temperature.
