Density, specific heat, melting point of soft solder
Are you interested in the density and specific heat 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. The price is optimal.
Wettability
The essence of the phenomenon is that the melt must completely spread over the surface of the soldering zone, tightly filling all gaps and not forming gaps. This can only be accomplished when the solder metal has a stronger bond between the molecules of the solid than in the liquid;
melting point
It must be higher than the permanent operating temperature of the solder joint, but lower than the temperature of the workpieces to be joined. An important characteristic of any solder is the actual crystallization temperature interval - between the beginning of alloy melting and its complete transformation into a liquid. Only after complete solidification the solder joint can be subjected to the necessary loads, otherwise brittleness and increased electrical resistance can cause destruction of the solder joint;
Toxicity
The solder composition must contain a specified minimum of toxic substances, which include zinc (its vapors are poisonous), lead and tin powder. Supplier Evek GmbH offers to buy soft solder at an affordable price in a wide range. Provide product delivery anywhere in the continent. The price is optimum.
