Silver SoldersAll silver solders meet the relevant international standards. Certificates of Conformity are readily available. The materials are available as wire, rods 1.0mm - 5.00mm dia, strip, foil, powder and paste.
Silver soldering is a brazing process.
The components must have a degree of overlap as it relies on molten alloy flowing into a joint gap by capillary action. Only in this manner will the full benefits of the process be attained.
Lowering the silver content of the alloy leads to; higher brazing temperature (higher service temperature) wider melting range (better gap filling properties) larger fillets and lower alloy cost per kg.
Care should be taken when brazing some types of stainless steel. If the joint is in contact with water joint failure through crevice corrosion could occur. This will not occur if the steel is an austenitic grade ie it contains nickel. A simple check is to use a magnet. They are non-magnetic.
The flux used must be compatible with both the melting range of the alloy and the parent materials. HT5 flux is recommended.
All alloys are manufactured from virgin metals to ensure they there is no contamination. They are analysed prior to extrusion and drawing. Rods are melted in "flow tests" to ensure uniform brazing characteristics.
