Bimetal Strips
Bimetal Consists of Copper(Sheet metal) cladded on pure Aluminum(Base metal), both metal being diffused together to form an inseparable whole by rolling bonding process. Bimetal , is therefore not and alloy and copper layers are not electro Plating but are rather mechanically welded Aluminum Sheets .
Bimetallic Strips. Bonding two metals with dissimilar thermal expansion coefficients can produce useful devices for detecting and measuring temperature changes. A typical pair is brass and steel with typical expansion coefficients of 19 and 13 parts per million per degree Celsius respectively.
bimetal plates
Bimetal plates and washers are used for connections between copper conductors and aluminium one's, in order to avoid corrosion that makes connection ineffective and unreliable.
Being copper and aluminium materials with different electrical potential, the contact between the two generates a galvanic cell in presence of an electrolyte (typically humidity), with deterioration of the less noble material (aluminium) and with rapid decay of electric capacitance of the contact surfaces (stack effect ).
bimetal washer
The interposition of a bimetallic Cu-AL plate or washers prevent the onset of the problem: since these products are bimetallic (obtained by explosion welding), the copper and aluminium surfaces are molecularly linked, without the presence of an electrolyte that can trigger.
Bimetallic elements consist of copper plated aluminium plates. Since the connection area of both metals is in the middle, it is kept away from air and humidity. This material enables a secure contact and a corrosion protected connection between copper and aluminium. Besides bimetallic plates and spacers we can also supply cut-outs with and without drillholes especially for your specific application
