Physical and mechanical properties. Scope of application of soft solder
Are you interested in the field of application of soft solder? The supplier Evek GmbH offers to buy soft solder in any quantity at an affordable price in a wide range. We provide product delivery anywhere in the continent. Price is optimum.
Technical Characteristics
The alloys under consideration should have good liquid flowability when melting, as well as good wetting of the surfaces of the metals connected with each other. Despite the low (up to 120 ... 150 ° C) of its melting temperature to the soft solders have special requirements that relate to the mechanical strength and resistance to the adverse effects of the environment (meaning primarily corrosion). In addition, after soldering there should be no shrinkage stresses at the joint, and the thermal expansion coefficient of the final construction should be minimal.
Fabrication
Most soft solder brands are predominantly industrially produced, but in some cases, they can also be prepared by yourself, or by individual order. Soft solders with a melting point of less than 100...110°C can be produced in common porcelain crucibles, for harder alloys steel crucibles are used. Evek GmbH offers a wide range of soft solder at an affordable price. We provide product delivery anywhere in the continent. The price is optimum.
Stages of solder production
The purification and grinding of all components using ball mills;
Mixing in special dispensers;
Melting in induction furnaces in an oxid-free atmosphere, or in vacuum furnaces (to avoid slagging);
Casting the finished alloy in the molds;
If necessary, rolling of solders to wire or bars of trapezoidal cross-section.
