High pure High temperature Graphite Crucible For aluminium melting
1. Product description
High purity graphite: 99.99% Metal smelting metal stick So you do not waste your savings The main raw material graphite crucible is crystalline natural graphite. Therefore, it maintains the original natural graphite various physical and chemical properties. The use of special high purity graphite materials, high-strength, high-density graphite materials; excellent technical staff; precision CNC machining equipment, etc., can provide customers with excellent performance graphite crucible melting, casting crucible, graphite tank, trombone, pull tab pull rod graphite mold and other products. Selected special special materials, can make our products graphite crucible product durability than ordinary materials more than 2 times longer life, more can withstand more than 2000 ℃ high temperature!
But also has the following characteristics: 1 good thermal stability: graphite crucible for rapid thermal quench conditions of use, special formula. 2 good corrosion resistance, impact resistance, to ensure product quality and reliability. 3 good resistance to acids, alkalis. 4 good heat conduction properties: can greatly shorten the melting time, save energy. 6 less than 300pp ash, to ensure precious metals smelting is not and we also have other jewerly tool, welcome to contact us
2. Why choose graphite?
Graphite is a stable and reliable material with excellent strength at low and high temperatures. The thermal shock resistance eliminates spalling.
This crucible contains fixed carbon which gives a good thermal conductivity and thus reduces melting time, saving you both time and money. As the raw materials used are strictly controlled, impurity inclusion risk is eliminated. This graphite crucible has an ash residue rate of less than 0.1% ensuring that the metal is not contaminated during smelting.
Graphite crucibles can leave a residue on fingers, gloves or cloth. Clean carefully after each use as graphite can be hard to clean. Crucibles can crack or break if dropped or knocked. Ensure all appropriate safety.
