Copper CNC Machining | Chinese Manufacturer
Copper CNC machining refers to the use of computer numerical control equipment to cut, shape, drill, mill, turn, and finish copper or copper-alloy workpieces into precision components. It is widely used when a part must combine high electrical conductivity, high thermal conductivity, good dimensional accuracy, and a clean finished surface. Because copper is softer and more ductile...

Special Aluminum Extrusion
Special aluminum extrusion refers to non-standard aluminum extruded profiles designed for a specific function, shape, or dimensional requirement rather than selected from a catalog standard. In industry sources, these are described as special aluminum extrusion profiles with specific shapes and sizes, often produced with tight dimensional tolerances and made by a die designed for...

What is Brass Investment Casting
Brass investment casting is a precision metalcasting process used to produce complex brass components with good dimensional accuracy, fine detail, and relatively smooth surface finish. It combines the metallurgical advantages of brass with the geometric freedom of investment casting, making it well suited to parts that are difficult or inefficient to machine from solid stock. Brass...

Is Brass Magnetic?
In general, brass is not magnetic. Most brass alloys show little to no attraction to a normal magnet, because brass is primarily an alloy of copper and zinc, and neither element is ferromagnetic in the way iron, nickel, and cobalt are. In everyday terms, a standard piece of brass should behave as a non-magnetic metal. That said, the full answer is slightly more nuanced. Brass can...

6061 Aluminum Profile
A 6061 aluminum profile is a structural aluminum section made from the 6061 heat-treatable alloy family, one of the most widely used engineering aluminum grades for extruded profiles, bars, tubes, and custom cross-sections. It is favored because it offers a well-balanced combination of strength, weldability, corrosion resistance, machinability, and fabrication flexibility. In...

What Is Green Sand Casting?
Green sand casting is one of the oldest and most widely used metal casting processes. It uses a mold made from “green sand”, which is a mixture of sand, clay, water, and other additives. The word “green” does not refer to color; it means the mold is moist and unbaked In this process, a pattern is placed in sand, the mold cavity is formed around it, and molten metal...

Manufacturing and Processing of Cast Iron
The manufacture of cast iron is a tightly controlled metallurgical process, not a simple melting-and-pouring operation. Its final performance depends on a sequence of linked steps in which chemical composition, melt cleanliness, inoculation or treatment, mold design, cooling rate, and post-processing all interact. Because cast iron is highly sensitive to carbon behavior and graphite...

Surface finishing for precision castings
Shot / bead / sand blasting — fast, uniform matte finish; removes shell wash, sand, scale; good pre-step for plating or painting. Use small glass beads for smoother results; coarse grit for scale removal. Vibratory / barrel (mass) finishing — excellent for burr removal and edge radiusing of many small parts; economical for batches; finish depends on media + cycle time....
