SMT Tungsten steel nozzle performance and feature

Tungsten steel nozzle is made of tungsten steel material. As the tungsten steel with high hardness and high wear resistance, so tungsten steel produced with tungsten steel nozzle than other materials have a longer life nozzle.

Tungsten steel is a kind of cemented carbide, mainly composed of hard phase and binder phase of the powder metallurgy products. Hard hardness is very high, mainly a variety of carbides. Its main carbides are: tungsten carbide (WC), titanium carbide (TiC), tantalum carbide (TaC) and niobium carbide (NbC). In most cases, cobalt is used as a binder phase. As the tungsten steel has plasticity, so in the tungsten steel plant, tungsten steel nozzle to be mixed, pressed and sintered, the final mold made.

High hardness and high wear resistance Tungsten steel according to ISO standards. This classification is based on the material class (P, M, K, N, S, H) of the workpiece. Different tungsten steel materials have different uses, such as turning, milling, hole processing, thread processing, grooving and so on. Tungsten steel has a high hardness and wear resistance, commonly used in the manufacture of metal cutting tools, measuring tools, molds and so on. Usually when the material hardness is high, wear resistance is also high; bending strength is high, the impact toughness is also high. But the higher the hardness of the material, the lower the bending strength and impact toughness.

Tungsten steel nozzle composition ratio about 18% tungsten, high hardness and high wear-resistant tungsten steel hardness of Vickers 10K, second only to diamonds. For this reason, the tungsten steel nozzle has a characteristic that is not easily worn. High hardness and high wear resistance Tungsten steel for the production of suction nozzle, lathe tool, impact drill bit, glass knife head, tile cutter above. Tungsten steel nozzle has a high hardness, wear resistance, strength and toughness is good, heat, corrosion and a series of excellent performance, especially its high hardness and wear resistance, even at 500 ℃ temperature is basically not Change, at 1000 ℃ still have a high hardness.

Nozzle for LED packaging to overcome the bakelite nozzle, rubber nozzle and other materials, lack of life, and because of its plasticity, can be made smaller hole tungsten steel nozzle, Shenzhen has a 3mil Hole diameter, this tungsten steel nozzle for the production of 6mil-7mil small size LED, to overcome the chip is too small, resulting in grain edge broken angle, display for darkness, significantly lower the LED IR rate.
