The copper and aluminum foil material is placed at the bottom, then the composite resin material which is electrical insulator but thermally conductive, finally at the top the copper foil or laminate and then

Electrical Contacts Selection Guide

2020/8/17Graphite brush materials are used typically for high-power equipment. Metal brushes or sliding contacts are used for signal or low power applications. Electrical contacts consist of a high-conductivity, soft, and oxidation-resistant material, often with a second phase to provide anti-welding and/or arc-resistance.

A Guide to Selecting the Right Rod

These days graphite is produced using extremely high temperatures in a two-part process, one to create tensile strength and one for stiffness. Temperatures sometimes exceed 3000 degrees! Generally the hotter the furnace in each process the more tensile strength and stiffness the fibers have, which means you need less material to build a rod, and the rods you do build can be lighter and more

How to detect the purity of graphite material

2019/7/23To understand the main test methods for the purity of graphite materials, we must first clarify several concepts: Purity: The purity of graphite is the mass fraction of carbon in the graphite, usually expressed as 99%, 99.9%, or several 9. Ash: Residues of graphite, usually expressed in% form, after burning at high temperatures to completely
