Physical and mechanical properties. The scope of aluminum solder
Buy aluminum solders in a wide range of brands and sizes the company offers Electrocentury-steel. All products are sold at economically competitive prices from the manufacturer. The supplier ensures prompt delivery of solders at the address set by the customer.
Kinds of aluminum alloys
Due to the formation on the surface of aluminum products, inert oxide film, direct soldering possible only with the use of alloys, which include aluminum. Given that soldering is mainly used regarding cable products, practical use is made of the following brands of aluminum alloys:
34-A and 35-A: for applications with high mechanical stress on solder joints;
A and b: used for tinning the surface of the aluminum shells and cables
Cadmium: from toxicity of cadmium is rarely used, mainly for wires of small cross section;
П250А: used for tinning copper lugs connection with aluminum wire;
П300А: used for the same purposes, but because it has high resistance against corrosion, is used in soldering aluminum underground cables ;
П300Б: is used when implementing soldering, pouring, when the connection is made of copper wires with aluminum;
TSO-12, CA-15: used as substitutes П300Б solder when soldering the individual wires of aluminum and copper wires.
The company Electrocentury-steel offers at the affordable price of various brands of aluminum alloys. The provider ensures timely delivery of products to the address specified by the customer.
