Uruguay Medium coarse graphite

我公司生产的中粗石墨,最大粒径0.5mm、0.8mm,是我公司结合自身技术优势,在国内率先采用挤压成型工艺成功开发出的新型炭材料,产品的内部结构和性能指标完全有别于振动、模压成型的中粗结构石墨,技术难度大。产品性能指标达到国际先进水平。产品比普通石墨制品具有适宜的电阻率及均匀的结构,具有优良的耐化学腐蚀性和优异的抗氧化性能及高温稳定性,能够适应各种苛刻的高温环境,并在该环境下保持所需的机械强度。

Product Description

Brief introduction to produpts

The maximum grain size of our extruded graphite is 0.5mm &0.8mm. With advanced technology and our own experiences, we become the first one in China to use extrusion technology to develop this new carbon material. The structure and technical data of our product is completely diffetrent from vibration and molded graphite,and its specification has reached the international advanced level of extruded graphite.

Extruded graphrte has better properties compared with ordinary graphite, like suitable electric resistivity,homogeneous structure, chemical corrosion resistance, antioxidant properties, high temperature stability. It could work in various harsh environment of high temperature and maintain the desired mechanical strength.

Available sizes:

Rods: dia.169-500x Max.2600mm

Blocks:400 x 400 x Max.2400mm, 500 x 300 x Max.2400mm

Customized machined components
