Brass is an alloy composed of copper and zinc. Brass composed of copper and zinc is called ordinary brass. If it is a variety of alloys composed of more than two elements, it is called special brass. Brass is a copper alloy with zinc as the main element. As the zinc content increases, the strength and plasticity of the alloy increase significantly, but the mechanical properties will decrease significantly after exceeding 47%, so the zinc content of brass is less than 47%. In addition to zinc, cast brass often contains alloying elements such as silicon, manganese, aluminum, and lead. Casting brass has higher mechanical properties than bronze, but the price is lower than bronze. Cast brass is often used for general purpose bearing bushes, bushings, gears and other wear-resistant parts and valves and other corrosion-resistant parts. Brass has strong wear resistance. Brass is often used to make valves, water pipes, connecting pipes for internal and external air conditioners, and radiators.

Investment (lost wax) casting is a method of precision casting complex near-net-shape details using replication of wax patterns. Investment casting or lost wax is a metal forming process that typically uses a wax pattern surrounded by a ceramic shell to make a ceramic mold. When the shell dries, the wax is melted away, leaving only the mold. Then the casting component is formed by pouring molten metal into the ceramic mold.

The process is suitable for repeatable production of net shape components from a variety of different metals and high performance alloys. Although generally used for small castings, this process has been used to produce complete aircraft door frames, with steel castings of up to 500 kgs and aluminium castings of up to 50 kgs. Compared to other casting processes such as die casting or sand casting, it can be an expensive process. However, the components that can be produced using investment casting can incorporate intricate contours, and in most cases the components are cast near net shape, so require little or no rework once cast.

Silica sol casting process is the main steel investment casting process of RMC investment casting foundry. We have been developing new technology of adhesive material to achieve much more economical and effective adhesive material to build the slurry shell. It is a overwhelming trend that Silica sol casting process replaces the rough inferior water glass process, especially for stainless steel casting and alloy steel casting. Besides the innovated molding material, the silica sol casting process has also being innovated to much steadier and less heat expanding.
