Alloy UNS C10200 Copper Uses

Due to its excellent electrical and thermal conductivity, this alloy is often used in electrical components such as circuit boards, connectors, and switches. Due to its corrosion resistance properties, it can also be used in plumbing fixtures and electronic devices such as TVs and computers. Additionally, the C10200 Alloy can be used in automotive parts such as brake systems because of its strength and durability at higher temperatures.

C102 Corrosion Resistance

Copper C102 has excellent corrosion resistance properties, making it ideal for indoor and outdoor use where exposure to moisture or other corrosive elements may occur. It can resist most common acids except hydrochloric or nitric acid at concentrations over 5%.

C102 Heat Resistance

Copper C102 can maintain good mechanical performance up to 500°C (932°F), making it suitable for some high-temperature applications such as furnace components or heating elements where other alloys may not be able to withstand the heat without becoming brittle or losing their strength properties over time.

C102 Heat Treatment

C102 Copper Material does not require any additional heat treatment after fabrication since it already possesses the required mechanical properties without being exposed to additional heat treatments such as annealing or quenching processes before use in most applications where this type of alloy would be beneficial. However, there are certain cases where these processes may need to be completed depending on the application requirements; therefore, consulting with an expert before use is recommended if uncertain about what kind of heat treatments should be performed on the material before use.

C102 Machining

C102Machining Alloy c1012 requires special tools due to its high hardness rating. However, it can still be done with regular machine shop tools if extra care is taken during operations, such as drilling or tapping threads into the material surface area when fastening parts together using bolts or screws made from either stainless steel or brass hardware instead of aluminum hardware which might corrode over time due to contact with this type of material’s surfaces during assembly procedures like welding, etc.


CU1012 is an incredibly useful metal alloy thanks to its combination of mechanical strength, corrosion resistance, heat resistance, and ease of machinability, making it suitable for a wide range of industrial applications, including electronics manufacturing, plumbing fixtures construction, industrial furnace components production automotive parts manufacturing, etc. Its composition consists mainly of 99 95% copper combined with 0 05% oxygen, giving this material great electrical conductivity and other desirable characteristics allowing engineers, designers, architects, etc. To take full advantage of its unique set features when constructing products requiring strong materials capable of withstanding extreme conditions while maintaining their structural integrity under stress loadings, etc. All things considered, taking proper care during installation operations and choosing appropriate fastener materials when assembling components made from this particular type of material will ensure long-lasting, durable products capable of enduring even the harshest environmental conditions imaginable! Happy Machining :)!
