The Tai Xiye that start letter explains the melting point of stannic line for you

Be in what when buying stannic line, care most should not be the price however stannic line is pure, melting point is how many degrees! Generally speaking a bit better how much is the melting point of stannic line? Is melting point low still to had been nodded high very? Course of study of Xing Hongtai stannum explains the melting point superiority of stannic line for you below:

The bases of stannic line is stannum and lead, it is a kind of alloy actually, the physical character such as melting point, hardness is concerned with the quantity that contain stannum. The quantity containing stannum of soldering tin is in the 60% lowest when the left and right sides, it is more than 200 Celsius about.

Have silk of plumbic soldering tin:

The melting point that the melting point of silk of 1)63/37 soldering tin is silk of soldering tin of 183 ℃ 2)60/40 is 185 ℃ - 190 ℃

The melting point of silk of 3)55/45 soldering tin is 187 ℃ - the melting point of silk of soldering tin of 202 ℃ 4)50/50 is 190 ℃ - 216 ℃

The melting point of silk of 5)45/55 soldering tin is 192 ℃ - the melting point of silk of soldering tin of 227 ℃ 5)40/60 is 194 ℃ - 238 ℃

The melting point of silk of 6)35/65 soldering tin is 198 ℃ - the melting point of silk of soldering tin of 247 ℃ 6)30/70 is 202 ℃ - 256 ℃

Without silk of plumbic soldering tin:

The melting point of silk of 1)Sn-Cu-Ni soldering tin is 225 ℃ - the melting point of silk of soldering tin of 227 ℃ 2)Sn-Cu-Ag is 211 ℃ - 219 ℃

The melting point of silk of 3)Sn-Bi-Ag soldering tin is 205 ℃ - the melting point of silk of 208 ℃ 4) Sn-Zn soldering tin is 117 ℃ - 119 ℃

The melting point of silk of 5)Sn-Cu soldering tin is 220 ℃ - the melting point of silk of soldering tin of 222 ℃ 6)Sn-Ag is 221 ℃

The common stannic line cent on market is line of stannum having lead now (silk of soldering tin having lead) with line of the stannum that do not have lead (silk of the soldering tin that do not have lead) 2 kinds big, the multi-parameter such as its norms and melting point each are not identical.

Basically see alloy part, without plumbic Sn96.5% Ag3.0% Cu0.5% , because not be in all frit, so melting point is limits; is spent to have plumbic Sn63% Pb37% in 380-420, be in all frit, melting point is 320-380 is spent. In all frit is to show a few photographs drop in temperature to begin in all the dot of frit, said popularly, let a few kinds of objects become the bit more critical temperature of liquid state from solid state frit at the same time namely.
