Dart performance of different materials

 Dart sport is gradually accepted by the public because its technology is simple and easy to master, it does not need special venues and facilities, and the amount of exercise is appropriate, and it is not limited by age, gender, climate and other conditions. Darts can not only stretch muscles and bones, eliminate fatigue and enhance people's physical coordination, but also temper people's will and improve their psychological quality.

Darts can be made of a variety of materials. The performance and characteristics of darts made of different materials are different. In order to make more people better understand darts, here are some common dart materials:

Brass: ordinary brass is a copper zinc binary alloy with high density, good thermal conductivity, high plasticity and strength, good formability and wide application. Low melting point of brass; The hardness is generally greater than that of any metal in its components; The conductivity and thermal conductivity of the alloy are lower than that of any component metal; Strong corrosion resistance. Because brass is soft, darts are generally used as "indoor darts".best darts online

Silver nickel alloy: it is a kind of imitation silver alloy. Actually, it does not contain silver, but the alloy of nickel, copper and zinc. The material has good conductivity and thermal conductivity, strong resistance to metal transfer, arc burning and electric erosion, good wear resistance, high strength, good ductility and cutting ability, and the contact resistance is higher than that of silver. Silver nickel alloy darts are relatively light and have poor directionality.darts store

Tungsten alloy: tungsten alloy is a kind of alloy with tungsten as the matrix (W content 85-99%) and added with Ni, Cu, Fe and other elements. It has high density and a series of excellent characteristics, with a large proportion: the general specific gravity is 16.5-18.75g/cm3, high strength: the tensile strength is 700-1000mpa, strong ray absorption capacity: its capacity is 30-40% higher than that of lead, and the thermal conductivity is 5 times that of die steel; Small coefficient of thermal expansion: only 1 / 2-1 / 3 of iron or steel, good conductivity; It has good weldability and machinability. Because of its excellent functions, it is widely used in aerospace, aviation, military and other industries. The darts made of tungsten alloy have a series of advantages, such as heavy weight, small volume, corrosion resistance, wear resistance, good aerodynamic effect, durability and so on.darts supplies
