Polished Surface Tungsten Carbide Nozzle High Temperature
Resistance
Introduction:
Carbide nozzles are also known as tungsten carbide nozzles. The
commonly used hard alloy is a tungsten-cobalt alloy.
The tungsten-cobalt alloy is used with refractory metal tungsten
carbide as hard phase, and transition metal (Co, etc.) used as
binder phase.
It is prepared by powder metallurgy technology to be super-hard
alloy, with the advantages of high strength, high hardness, wear
resistance, corrosion resistance, high temperature resistance,
small coefficient of linear expansion, etc.
It is one of the excellent tool materials, widely used in many
industrial production and processing operations. Because its main
component is tungsten carbide, it is often referred to as tungsten
carbide products.
The excellent performance of tungsten steel nozzle core is
unmatched by other tool materials, especially for long-time
operation of conditions of high temperature and corrosion. Tungsten
steel produced by powder metallurgy process is good choice for wear
parts.
Technical parameters:
Carbide nozzle tungsten steel is according to customer's drawings,
mainly used for ball laser welding. The diameter of the micropore
is the highest precision of the entire nozzle. Vertical tolerance
and parallelism are required to maintain good tolerances. Precision
carbide nozzles require smooth inner walls. Tungsten-steel nozzles
for laser soldering require a good finish to ensure long-lasting
operation and to minimize sticking operations.

Advantages:
Tungsten steel nozzles used for high-precision equipment require
good physical stability as the basis, especially for
high-temperature, corrosion-resistant and long-lasting operation.
It is a good choice to use cemented carbide materials. From the
selection of raw materials to the completion of deep processing of
tungsten steel, each procedure will directly affect the performance
of the cemented carbide nozzle. As a cemented carbide production
and processing manufacturer, we have been committed to providing
high-performance cemented carbide products for the mechanical
