Inquiry (采购产品): Graphite, carbon coating We are manufacturing an air pump that will have the inner steel drum coated with something softer than aluminum, that can be up to .007" thick maybe? that will be resistant to methanol, water and oil with a temperature of up to 300 degree F. It is intended to act as a " gap or tolerance filler". The steel drum rotates inside the aluminum case and attains maximum seal by the coating wearing into the aluminum hole that seats the drum each end. We need a product to do this and a means of applying it to the drum in a reasonably precise manner. **** Hidden Message ***** Greg Zucco 22338 Shake Ridge Rd.
