Supply, price

The provider offers certified products. In the technical documentation included data on chemical composition and set the percentage limits of the additives. Supplier KMZ, supplies solder POS-90 at affordable price in a optimally short period of time from warehouses in Russia and Ukraine. The price matches the high quality of products.

The percentage composition of (GOST 21930−76)

Fe Ni S Al Cu As Pb Zn Sb Bi Sn
≤0.02 ≤0.02 ≤0.02 ≤0.002 ≤0.05 ≤0.01 8.826 — 11 ≤0.002 ≤0.05 ≤0.1 89 — 91

The high content of tin in the alloy lowers the melting temperature of the solder. The choice of solder composition depends on the type of the connected metals, the method of soldering.

Technical characteristics

Among other tin-lead alloys, this alloy gives a higher level of purity of the soldered connections.
