Tin - Sn63Pb37 Solder Wire - Wanlutong Metal Group

WanLuTong Metal is the world's first cross-border network platform for non-ferrous metals industry.
The aim is to provide a seamless solution for the non-ferrous metal product chain.
We are committed to creating online negotiation matchmaking, cross-border network procurement, warehousing and logistics, online multi-language interview and communication and a series of one-stop trading service platforms.
Tin electrodes are electrodes used for soldering. Soldering can be used for hermetic metal welding without requiring high temperature and pressure.
According to the liquidus temperature critical point, the solder strip has high temperature solder bar and low temperature solder bar:
The liquidus temperature is higher than the tin-lead eutectic melting point--183 degrees. The solder bar is a high-temperature solder bar. The high-temperature solder bar is a solder bar formed by adding a high proportion of silver, antimony or lead to the solder alloy. The high-temperature solder bar is mainly Component assembly for no change when the motherboard is assembled;
The solder bar with a liquidus temperature lower than the tin-lead eutectic melting point--183 degrees is a low-temperature solder bar. The low-temperature solder bar is a solder bar formed by adding antimony, indium and cadmium to the solder alloy, and is mainly used for resistance of microelectronic sensors. Assembly of parts with low heat.
63/37 solder bar composition, 63% tin content, 37% lead content. It is specially designed for double wave soldering and single wave soldering, and manual dip soldering. For wave soldering and hot dip soldering, the operating temperature is 220 ° C -260 ° C.
The 63/37 solder bar has the following advantages:
☆ Excellent wettability, reducing the occurrence of bad solder joints;
☆ Very few harmful impurities, which can increase the diffusion force and enhance the liquidity;
☆ The solder joints are brighter;
☆ The liquid surface is bright and the tin slag is less;
☆ The quality is consistent and the soldering effect is stable.
63-37 solder bars are widely used in the electronics manufacturing industry and are ideal for soldering soldering on wave soldering and hand-fired circuit board inserts.、
Internet + collectivize direct sale of nonferrous metals. It is a high-tech enterprise integrating smelting, spectral analysis, casting, extrusion, stretching, processing and eddy current testing of non-ferrous metals such as copper, aluminum, zinc, magnesium, nickel, cobalt, tin, lead and cadmium.
Business scope: Enterprises strictly in accordance with international standards to produce copper, aluminum products and copper alloys, tin bronze, phosphorus bronze, lead bronze, aluminum bronze, silicon bronze, manganese bronze, beryllium bronze, aluminum alloy, magnesium alloy, nickel alloy, tin alloy, titanium alloy, zinc alloy, molybdenum alloy, zirconium alloy and other materials such as plate, coil, foil, strip, bar, tube, ingot, profiles.
Wanlutong Metal Group has a professional large-scale production base, which uses German imported direct reading spectrometer, Japan universal tensile testing machine, Brinell digital hardness tester, Swiss imported eddy current flaw detector and other international advanced testing equipment to strictly control the material of the product. , hardness and various mechanical properties.
Lead-free solder bars, lead solder bars, tin-silver solder bars, 63╱37 solder bars, tin-silver-copper solder bars, high-temperature solder bars, low-temperature solder bars, etc., which are produced in strict accordance with international standards, have passed the Internet + grouping Non-ferrous metals are sold online to the world.
