Sell tungsten wire

Description

As a high performance materials, Pure Tungsten has high melting temperature, high density, low vapor pressure, low thermal expansion combined with good thermal conductivity, sufficient electrical resistance, high modulus of elasticity. Surface finish is supplied 1: Black, as drawn condition, where drawing lubricants and oxides are retained on the surface, 2: Cleaned condition by firing in hydrogen or electrochemical etching. Direction for Use: 1. Aquadag layer on the surface of wire should be removed before using the wire is not suitable for contacting with iron, nickel, carbon, when the temperature is higher than ***0. The wires should be preserved in dry room, in which the relative humidity should not surpass *5%, and keeping away from acid or alkali atmosphere. 2. Cleaned wires should be preserved in dry vessels.
