    QT-6040T Lead Solder Bar Advantages

    Less welding slag, reliable, suitable for welding spot.

    The production of solder bars in Qiantian tin factory is different from the general casting process, because a large amount of solder slag, or non molten tin, will be produced in the wave soldering furnace by the general casting process. In the process of operation, it is easy to produce large lumps of solder like tofu dregs, and the melted solder surface will be transformed into yellow and brown solder blocks in a short time.

    In order to avoid this kind of situation, Qiantian tin factory adopts unique melting, casting, extrusion process, processing special metal alloy formula, selects high-purity refined tin, pure lead and high-grade anti-oxidation alloy as raw materials to ensure the high purity of Qiantian brand anti-oxidation solder bar, even if it is used in wave soldering furnace or hand immersion furnace for a long time.

    It can effectively control the surface and internal tin content of the metal, avoid a large amount of tin slag, control the tin slag to a small amount, and keep the solder liquid level in the soldering furnace bright as a mirror in the process of wave soldering or manual immersion welding. Our company uses refined tin to make lead solder bar, which has the following unique advantages:

    1. The surface of lead solder strip is uniform and smooth, with high purity, good fluidity and wettability after melting, bright solder joint and little oxidation residue;
    2. Low cost, excluding high price precious metals;
    3. It can adapt to the temperature that the existing wave soldering equipment and components can bear;
    4. The sensitivity to impurity elements is low;
    5. The surface concave convex phenomenon is less when cooling;
    6. The reliability of solder joint is higher than that of SnPb solder.

    QT-6040T Lead Solder Bar Features

    Pure tin, pure copper and pure silver are used as raw material

    According to the required alloy, it is made of pure tin, pure copper, pure silver, etc. combined with high-grade antioxidant essence. The quality of finished products is determined by the quality of incoming materials.

    Full strength

    Pure tin, electrolytic tin and pure lead are used as raw materials to ensure sufficient degree and weight, which can be sent to a third party for testing.

    Less slag and strong oxidation resistance

    Low melting point, good fluidity, sufficient antioxidant elements, little slag, good welding effect.

    Source factory, sufficient inventory, complete models

    The factory stock has the guarantee, the variety is complete, the delivery speed is fast, after-sale has the special person service.

    The solder joint is bright, firm and full

    The solder joint is bright and full, with good oxidation resistance, good wettability and expansion tension, and the solder joint does not produce overseas Chinese pull point.

    Extensive Use

    It is suitable for welding led, household appliances, electronic components, computers and other products.
