Low-melting, non-cadmium silver solders in the form of rods with flux coating

Kurzfassung

A Polish institute offers silver solders in the form of rods. Solders are designed for manual flame soldering of high alloys - structural and stainless steels, and copper and its alloys. The coating has adequate mechanical resistance, and its thickness is selected to ensure the required technical properties of the solder. Partners for cooperation sought: metal and machine building industry.

Details

Silver solders are in the form of rods 2x450 mm in diameter of following grades: AG 102 (B-Ag54CuZnSn-620/650), AG 104 (B-Ag45CuZnSn-640/680) or AG 106 (B-Cu36Ag34ZnSn-630/730) in accordance with PN-EN 1044:2002 with low fluoride flux coating FH10 in accordance with PN-EN 1045:2001.

Innovative Aspects:
Unlike solid filler metals, coated solder does not require special preparation and use of additional flux. While soldering with the use of such materials, the flux and solder are batched into the joint area through melting of the coated rod. For silver solders AG 102, AG 104 and AG 106 toxic and carcinogenic cadmium is replaced by tin. They have lower melting temperature than commonly used silver solders with copper and zinc with the same contents of silver. Brazing of unalloyed, high-alloyed steels (stainless and structural steels), copper and its alloys. Examples of application: air conditioners and cooling systems, heating systems, fittings, measuring devices, hydraulics, metal articles, household equipment, etc.
