Aluminium Oxide Thread Guides
We become reliable manufacturer and supplier of Aluminum Oxide Thread Guides. The offered aluminum oxide is a hard material which is sluggish to all acids and alkaline solutions utilized as a part of textile enterprises. It is a decent heat conveyor and is near metals in term of thermal conductivity and direct expansion. This Aluminum Oxide Thread Guide is available with matte, ground and cleaned surfaces can be created with a general resilience of 0.2mm or 2%. Products with littler endurance can likewise be made according to the customer's necessities.
