Grade K30 K40 Tungsten Carbide Nozzle of Inner Hole Diameter 0.6 0.7 0.8 0.9mm

This tungsten carbide (WC) nozzles looks simple but it has big manufacture difficulties:
innner hole Φ0.8mm with ±0.025 tolerance and 0.4 mirror surface finishing.
Our processing technology will support ±0.001mm as per OEM request.
Ball, funnel and bore polished.
Undercut DIN509 E 1.0x0.2
This series ID contains 4 different measures:
Ø7/0,6x32mm
Ø7/0,7x32mm
Ø7/0,8x32mm
Ø7/0,9x32mm
two ends R7 curved surface, carrying 45° angle.
The locking groove at one end is designed to make the nozzle stuck in the machine without any unexpected movement.
These nozzles are sold in regular orders of large quantities for European market. You are more than welcome to customize your perfect nozzles.
European customer said after testing more than 50 supplier's nozzle samples, we are the only manufacture who can ensure all the size tolerances measuring and inspection.

Key Points:

Basic properties:

1. High hardness and high wear resistance

2. High elastic modulus

3. High compressive strength

4. Good chemical stability (acid and alkali corrosion, high temperature oxidation)

5. Low impact toughness

6. Low expansion coefficient. The thermal conductivity and electrical conductivity is similar to iron and its alloys.

Safe packages:

The tungten carbide nozzles are wrapped with pearl cotton and plastic case, then packed by corrugated carton boxes.

Certificates:

Zhuzhou Sanxin Cemented Carbide Manufacturing Co., Ltd.

A reliable and professional wolfram carbide nozzles, spray head parts manufacture with custom services.

We mainly cooperate with China national laboratories.

In April 2022, China Lunar Exploration Project, our cooperation begins with a kind of tungsten carbide drilling part for China lunar rover named 'Jade Rabbit' Chang'e-6. The samples work well, after two months of efforts, we finally put the carbide drilling part processing out.
