C18150 Description

It has good electrical conductivity, thermal conductivity, high hardness, wear resistance, blast resistance, crack resistance and high softening temperature, less electrode loss during welding, fast welding speed, low welding total cost, suitable for welding machine electrode related pipe fittings, but the performance of electroplating parts is general

C18150 Introduction

Chromium-zirconium copper is a wear-resistant copper, with excellent hardness, excellent electrical conductivity and good temper resistance, good upright, thin sheet is not easy to bend, is a good aviation material processing electrode hardness 75(Brinell) density 8.95g/cm3 electrical conductivity 43MS/m softening temperature 550, Generally used for making welding machine electrodes with operating temperature below 350. The commutator plate of the motor and other kinds of work at high temperature require high strength. Hardness, electrical conductivity and conductivity parts, also can be used in the form of bimetal brake discs and disks. CuCrlZr, ASTM C18150 C18200

A copper chromium zirconium alloy C18150(CuCr1Zr) conforming to RWMA Class 11 which is used mainly for resistance welding application but also other applications which require high electrical conductivity properties with a degree of wear resistance and a higher strength than pure copper.The alloy can also be specified to BS 2872/2874 CC102, EN 12165/12420 and Din 17673/17678-1 W Nr 2.1293.

Ciri-ciri Utama

Aloi kuprum tinggi dengan tambahan kecil kromium dan zirkonium, yang boleh dirawat haba dengan pelindapkejutan dan pengerasan pemendakan. Penambahan Zirkonium membantu mengelakkan elektrod melekat semasa kimpalan titik keluli tergalvani.

Kegunaan Biasa

Aloi kuprum tinggi dengan kekonduksian elektrik dan haba yang sangat baik yang diperkukuh oleh rawatan haba.

Elektrik
Aplikasi utama adalah untuk penyambung elektrik, gear suis dan pemutus litar yang memerlukan sifat mekanikal yang lebih tinggi. Ia juga digunakan dalam penjana untuk bar komutor dan gelang hujung untuk motor elektrik.

Mekanikal/Elektrik
