Chengdu Artech Specialty Graphite Co.,Ltd is one of the leading China graphite heating element manufacturers and also a professional graphite heating element supplier, welcome to import products from our factory.Product name: Graphite Heating element Graphite heating element for vaccum furnace Material: high pure graphiteSize: customizeApplication: high temperature and vaccum furnaceDensity: 1.65-1.88 g/cm3Compressive strength: 30-240MpaFlexural strength:7-85MpaSpecific electrical resistance:6.5-15μΩmBrand Name: OEMMOQ: 1 pcsDelivery date: 20 daysPackage: Polywood or custom packageFunction:1.Graphite Heating element have high thermal stability.Graphite does not melt but sublimes at about 3627 ℃ .2.Graphite Heating element have good electric conductivity.As temperature rises, electrical conductivity increases. 3.Graphite Heating element have high thermal conductivity.The thermal conductivity of graphite is higher than that of many metals and falls with increasing of temperature. 4.Graphite Heating element can resist thermal shock. so rapid heating or cooling is not a problem.5.Graphite Heating element can resist corrosion.It can be widely used in acid based environments.6.Graphite Heating element are not wetted by molten glass or by most molten metals.7.The tensile,compressive and flexural strength of Graphite Heating element are very high.8.Graphite Heating element have high purity. Graphite can be purified to 20-30 ppm in block or less than 5 ppm for the finished items.
