Physical and mechanical properties. The field of application of soft solder.

Are you interested in the properties and application of soft solder? Supplier Avlob offers to buy soft solders at a bargain price. The supplier guarantees the timely delivery of products to any address in Europe or abroad. Regular customers receive a discount discount. The price is the best in this segment.

Technical specifications

The considered alloys have good fluidity during melting, they well wet the surfaces of the parts to be joined. Despite the low melting point (up to 120… 150 ° С), special requirements are imposed on soft solders, which relate to mechanical strength and resistance to adverse environmental effects (primarily, corrosion is meant). In addition, after soldering, there should be no shrinkage stresses at the junction, and the coefficient of thermal expansion of the finished structure should be minimal.

Manufacturing

Soft solders of most brands are produced mainly on an industrial scale, but in some cases they can be cooked either independently or by individual order. The production of solders, the melting point of which does not exceed 100… 110 ° C, can be performed in ordinary crucibles from porcelain, for the production of more refractory alloys, steel crucibles are used.

Technology of production of solders

  1. Cleaning and grinding of all components using ball mills;
  2. Mixing in special batchers;
  3. Melt in induction furnaces in a non-oxidizing atmosphere, or in vacuum furnaces (to eliminate slagging);
  4. Casting of the finished alloy into molds;
  5. If necessary — rolling solder to the condition of wire or bars trapezoidal cross section.

Company Electrovek-steel offers to buy at affordable prices from the manufacturer soft solders of any brand and profile. The supplier ensures the timely delivery of products to any point set by the consumer.
