Tungsten alloy fish pendant density, making it significantly smaller than conventional lead fish pendant. As the body Small size, so only need to spend some fish pendant. tungsten machined parts pellets higher hardness than lead , not card Main fish jawbone . The shape can be maintained more durable . High density tungsten alloy makes fishing becomes more Plus simple . Tungsten alloy pellets and sensitive , allowing you to easily feel what or with your Bait hit something, such as bushes , rocks , mud and so on. Lead is toxic and causes environmental pollution . Tungsten has the advantage of non-toxic and pollution-free , the Tungsten has replaced the lead, making it an ideal material for fishing sinkers .
Molybdenum carbide has a high melting point and hardness, good thermal stability and mechanical stability, and excellent corrosion resistance and other characteristics. Molybdenum is a silvery white refractory metal, a melting point of 2615 ℃, density of 10.2 g / cm 3, the expansion coefficient is small, a special tube is almost the same coefficient of expansion of the glass. Molybdenum stable at room temperature is higher than 600 ℃, rapidly oxidized.
