What Are the Specifications of Tungsten carbide needles?

The specifications of tungsten carbide needles usually include the following aspects:

1. Dimensions: including needle length, diameter, angle and other parameters, which vary according to different application requirements.

2. Hardness and wear resistance: The hardness and wear resistance of tungsten carbide needles are important performance indicators. These indicators vary according to factors such as the composition of tungsten steel and the heat treatment process.

3. Accuracy: The accuracy of tungsten carbide needles includes dimensional accuracy, shape accuracy and surface roughness. These indicators have an important impact on the processing quality and effect.

Specifically, some common tungsten carbide needle specifications include:

1. Diameter: ranging from 0.01mm to several millimeters, commonly used ones are 0.1mm, 0.2mm, 0.3mm, etc.

2. Length: ranging from several millimeters to tens of millimeters, commonly used ones are 5mm, 10mm, 20mm, etc.

3. Angle: There are tungsten carbide needles with different angles such as straight head, elbow head and ball head. The selection of angle needs to be determined according to the processing requirements.

4. Other parameters: such as surface roughness, tensile strength, yield strength, etc. These parameters are determined according to specific usage scenarios and processing requirements.

The specifications and performance parameters of tungsten carbide needles will vary depending on the manufacturer, production process, usage requirements and other factors. Therefore, when selecting tungsten carbide needles, you need to choose based on the actual situation.
