The price of tin wire
is mainly determined by its alloy composition, technical difficulty and production difficulty. The more commonly used lead-free tin wires in the market include silver-containing lead-free tin wires and conventional lead-free tin wires. Silver is a precious metal, so the higher the silver content of the tin wire, the higher the price. The composition of conventional lead-free tin wire is Sn99.3%Cu0.7%, which is the lowest price lead-free tin wire. In terms of technical difficulty, because the market is very mature, it is not very difficult. Compared with the special solder paste for stainless steel, the technical difficulty is relatively large, so the price of this solder paste is relatively higher than other solder pastes. . If the production is difficult, the low-temperature tin wire in the lead-free tin wire is a tin-bismuth alloy, which is relatively brittle and difficult to produce, and its price is several times higher than that of the ordinary tin wire.
The above is the pricing standard of lead-free tin wire, so the price of some lead-free tin wire in the market is the same, why the price is very different? There are many factors for this:
1. Brand factor, the price of high-quality brands is mostly higher than that of ordinary brands.
2. The weight of the product is different. The general packaging includes 500G/roll, 800G/roll, 1000G/roll, etc., and the price difference between different packages will be relatively large.
3. The middlemen take the goods and the manufacturers take the goods. I don’t know which hands the middlemen come from. There are profits in the middle links, and the price is naturally high.
4. The quality of the goods is different. Although they all say the same metal composition, some goods are processed from recycled materials, and their components cannot meet ROHS and other standards, but the price will be much lower.
