YG6 Cemented Carbide Expansion Head for 1.5HP AC Copper Tubes

YG6 Cemented Carbide Expansion Head Φ7mm Copper Tube Exclusive for 1.5HP Air Conditioner

Air conditioning expansion joints are special tungsten carbide tools mainly used to expand the ends of copper tubes into a bell mouth or cup mouth during the maintenance and installation of refrigeration equipment (such as air conditioners and refrigerators) to ensure the tightness of pipe connections.

Introduction:

A dedicated expansion head made of YG6 cemented carbide (94% WC-6% Co) with 89.5HRA toughness and hardness + 18° optimized blade angle is used to solve the problems of copper sticking and chipping in high-speed steel, achieving zero leakage expansion of φ7±0.1mm copper tubes at the million-level.

Advantage:

Mirror-finish conical polishing
- Diamond wheel precision grinding (Ra ≤ 0.2μm)
- Electrolytic passivation to eliminate microcracks

Gradient coating technology
- Ion-bombarded transition layer (bonding force > 60N)
- CrAlN coating thickness 3±0.5μm

Dynamic thermal compensation structure
- Embedded copper alloy heat sink (operating temperature < 150°C)
- Coefficient of thermal expansion matching copper tube (16.5×10⁻⁶/K)
