Product Name:
High Gravity Alloy Products
Model:
High Gravity W based Alloy Products
Product Details:
High Specific Gravity Alloy is a kind of matrix with W-based Alloy (W content of 85-99%), and add there is Ni, Cu, Co, Mo, Cr and other alloy elements. By alloy composition characteristics and uses are divided into W-Ni-Fe, W-Ni-Cu, W-Co, W-WC-Cu, W-Ag and other major series, and its density up to 16 .5-19.0g/cm3, were the world known as the high proportion of alloy.
It also has a series of excellent properties, than the major: general accounting for 16.5-18.75g/cm3, high strength: tensile strength of 700-1000Mpa, a strong ability to absorb rays: its ability to lead than the 30-40% high, thermal conductivity coefficient: Die Steel for 5 times; thermal expansion coefficient small: only 1/2-1/3 of iron or steel, a good conductive properties; has good weldability and workability. Given the high proportion of the above-mentioned alloy has excellent features, it has been widely used in the aerospace, aviation, military, oil drilling, electrical instrumentation, medical and other industries.
Application :
1.Tungsten alloy fishing sinkers Series : Environmental Friendly Material
1) Advantage: pollution-free, in line with international environmental standards, small volume, high-resistant to strong winds, entry water lightly, sinking fastly, is the best alternative to lead sinkers, best-selling Europe and the United States and other developed countries.
2) Type : ball type, bullet type, droplet-type, tube-type, semi-drop type, there is cylindrical hole, also could be painted with colors: Pink, Black, Yellow, White, Orange, Cool Blue, Green, Glowing or coated Gold, Silver, Copper and so on.
2.Tungsten beads, tungsten ball series: dia.1.5mm-dia.10mm accuracy of ¡À 0.01mm, for the fish falling weight, cluster bombs, medical equipment weights, shotgun projectile; dia.0.1mm-dia.10mm accuracy of ¡À 0.1mm, used in oil drilling balance , shotgun projectiles. The advantages: nuisance free, international environment protection standard, small body, high density.
3.High-density tungsten alloy weights Series: Machinery used in the balance hammer; oil drilling rod weight; Darts rod; golf weight block; racing weight block; mobile phone, game consoles Oscillator; aerospace gyroscope ; watches bob; balance weight ball; Earthquake Arbor.
4.Medical-ray shielding materials tungsten alloy series: 1, tungsten alloy grating blade; 2, tungsten alloy tank protection - on for medical radioactive shielding wall; shielding needle - used in medical liquid radioactive shielding; tungsten alloy memory - used storage of radioactive materials in cans, cartons and other containers. 3, collimator - for medical linear accelerator and nuclear technology applications in the tungsten alloy series Detect container system collimator; Co60 other radiation shielding.
5.Electric Materials Series: EDM electrodes, and resistance welding electrodes; a high proportion of electric contact, the contact of air circuit breakers.
6.Military Series: projectile, shrapnel, ball, rod, square tablets, cylinder, and other tungsten alloy block upsetting electricity, nuclear technology application in the tungsten alloy.
