- Sand Casting
Casting Quality focus on Metal Parts industry, we provide professional service in Metal Casting field.
Sand Casting is a popular metal form method, are suitable for all materiel, such as grey iron, ductile iron, malleable iron, carbon steel, stainless steel, aluminum and bronze.
- Investment Casting
also named as precision lost wax casting, mainly suitalbe for carbon steel and stainless steel parts. We also provide grey iron and ductile iron and aluminum and bronze parts by investment casting. It can achieve the best appearance with good tolerance
- Shell Casting
Shell casting method is a good option to replace investment casting and sand casting. the quality is better than sand casting parts, suitable for bulk production.
- CNC Machining
CNC Milling, CNC turning with 5 xix CNC center, we provide precision machining for all castings based on customers design drawings.

CD4MCu Casting Tensile Requirements: WWW.CASTINGQUALITY.COM
Tensile Strength, min100ksi [690Mpa]; Yield strength, min 70Ksi [485Mpa]; Elongation 16%
CD4MCu Casting Heat treatment process: WWW.CASTINGQUALITY.COM
Heat to 1900°F [1040°C] minimum, hold for sufficient time to heat casting uniformly to temperature, quench in water or rapid cool by other means.

CD4MCu is widely used in pump industry, especially in abrasive applications, such as pump casing and pump impeller. And CDM4Cu won’t pit like regular stainless steel, has a better stress/corrosive cracking resistance than standard stainless, and higher strength than standard stainless steel. And compared with regular cast iron material, it is much more resistant to corrosion and much stronger.
We made mistakes to name CD4MCu as SS2605 in our first revision, if you find any SS2605 in google, they coped our mistakes yet.
