Brass,Bronze,Copper Casting

As defined by its main properties, copper offers excellent electrical and heat conductivity, and good corrosion resistance ability as well. But native copper is rarely to be used, it usually exists to be a copper-based alloy so that the other elements can help greatly reduce the casting defects.

Copper Casting Overview

Copper casting alloy is a widely used casting alloy material in the industry. Copper alloys are widely used in shipbuilding and chemical industries because of their good corrosion resistance to fresh water, seawater, and certain chemical solutions. Copper alloys also have good thermal conductivity and wear resistance, so they are often used in the manufacture of various machines to withstand heavy loads and high-speed operation of the shaft of the sliding shaft bushings. Besides, copper casting can be used to manufacture casting copper jewelry.

Description of Copper Die Casting

Copper die casting is a high-temperature die casting method that fills the cavity of the die mold with liquid copper or copper alloy at a high rate under high pressure, causing them to solidify under pressure to form complete copper high-precision die casting. While both copper casting and squeeze die casting are used to produce copper parts, they are different processes that involve different methods and techniques to achieve different results.

Copper casting can involve various casting methods, while silica sol casting is a specific type of investment casting process that typically results in high-precision and high-quality parts.

Advantages: high accuracy of the copper casting, the possibility of producing parts with complex structures, and high production efficiency suitable for mass production. 

Disadvantages: Because of the high temperature (900-1100 degrees) and high density, copper casting has high requirements for equipment, molds, material melting, and other processes. 

Precise Brass Casting Molds

Casting brass is used to produce brass casting molds. Brass casting molds are widely used in machinery manufacturing, ships, aviation, automobiles, construction, and other industrial sectors, and occupy a certain portion of the heavy non-ferrous metal materials, forming the casting brass series.

There are some differences between the alloys of casting brass due to the melting point, fluidity, solidification shrinkage, sensitivity of the melt to gas, volatility, and thermal cracking tendency, so the applicable casting methods are also different.

The casting methods for casting brass mainly include die casting, sand casting brass, centrifugal casting, continuous casting, and brass investment casting. Different alloys need to be selected in a targeted manner. As a casting manufacturing company, Ray Force provides high-quality brass casting molds. Besides, our company can custom brass casting for customers. 

Bronze Molding VS Brass Casting Molding

Cu-Sn alloy volume shrinkage is very small (line shrinkage of 1.45% to 1.5%), which is easy to make complex bronze casting with accurate dimensional requirements and clear pattern crafts made by bronze casting for artists. Casting tin bronze generally also adds zinc, lead, phosphorus, and other elements. Zinc can improve the fluidity of the alloy, and reduce the tendency of tin bronze anti-bias. Lead significantly improves the wear resistance and machinability of the alloy. Cast in bronze is used for wear and corrosion-resistant parts.

Brass has a small solidification temperature range, good fluidity, and easy melting. As brass has the above characteristics of high strength, low price, and good casting performance, so brass has more varieties, greater production, and wider application than tin bronze and aluminum bronze in copper alloy.
