Copper (Copper symbol Cu) is the first metal used by humans more than 10,000 years ago, it is said that it took another 5,000 years for copper to lose its unique position as the only metal on the planet when gold first appeared. Copper is used for household items, decorations, weapons and tools in agricultural production. Apmetal will provide an overview of the applications and advantages of Copper and Copper alloys to help you choose the most suitable material.

In the non-ferrous metal industry, copper, brass, and copper alloys are always the preferred materials thanks to their superior properties and diverse applications. From copper sheets, copper wires, round copper bars to copper nickel tubes with typical materials according to popular Jis standards such as C1100, C1200, C2680, C2700, C2800, C3602, C3604, C70600... with common hardnesses O-H-1/2H-3/4H-EH... Each type brings its own unique value.

1. Red copper C1100 | C1200 - King of thermal and electrical conductivity copper.

 Outstanding advantages:

 - With high purity (>99.9% Cu), C1100 and C1200 have the lowest resistivity among red copper types.

 - Good corrosion resistance in fresh water and air environments.

 - Easy to process, can be rolled into copper sheets, drawn into copper wires, easy to bend and not cracked.

 - Outstanding toughness, resistant to impact and cold deformation.

Practical applications:

- The most common application is copper busbar - Copper busbar is often placed in electrical cabinets, as a conductor bar to distribute high currents. They are also used to connect high voltage devices in transformer stations and low voltage in battery clusters...

- Copper magnet wire is a high purity copper wire, excellent conductivity with a copper content of more than 99.99%, has good adhesion, good abrasion resistance, good heat resistance, so they are often used in oil transformers, dry transformers and welding machines.

- C1100 copper plate is mainly used in the Lithium battery manufacturing industry, architecture and CPU heat sinks.

- Copper wire 1200 is often used in the production of high voltage electric cables, motor wires, and the automobile and motorbike industry.

- Red copper pipe: Often used in the refrigeration industry, gas systems, medical...

2. Brass C2680 | C2700 | C2800: Multi-purpose "fake gold" alloy.

Outstanding advantages:

- Cu-Zn ratio = 65-35 (C2680) or 70:30 (C2700), they have better seawater corrosion resistance than red copper.

- High hardness, easy to CNC machining, ideal for mechanical processing.

- Beautiful, shiny golden copper color, long-lasting anti-tarnish.

- Cheaper price than pure red copper.

Common applications:

Brass is widely used in the electrical industry, the switching equipment industry, the decoration industry, the defense and railway industry, the engineering industry, the spring industry...

3. Free cutting copper alloy (C3602, C3604).

Known as the "King of CNC machining", this copper alloy has the following technical advantages:

- Contains lead (Pb 1.8-3.7%) in common forms such as round copper bars, copper wires, has smooth cutting properties, does not stick to knives.

- High surface gloss after machining, saving polishing steps.

- Good resistance, no deformation when tightening.

Industrial applications:

- Copper grade C3604 is widely used in the production of faucets, water equipment and supplies, pneumatic accessories...

- Copper grade C3602 is often produced into hexagonal bars for the processing of bolts, screws, and copper nuts in automated machinery.

Recommendation: Do not use C3604 material in drinking water systems because this type of copper contains many metals such as lead, it is recommended to replace this material with C69300 copper (lead-free).

4. Copper nickel tube C70600 (Cuni 90/10). Considered as "Armor" against seawater corrosion.

Advantages:

- Accounting for 90% Cu - 10% Ni, it has anti-corrosion and anti-pitting properties in seawater environment.

- Withstand high temperatures (up to 400 degrees C), withstand high pressure.

- Antibiotic, they can prevent algae or barnacles.

Intensive applications of Copper nickel:

- Used as heat exchanger tubes on ships, petrochemical refineries.

- Cooling system for nuclear power turbines

- Water pipes in marine environment.
