Copper strip is a rolled copper material that ranges in thickness from 0.5mm (0.019685 inches) to 10mm (0.393701 inches). Based on the company manufacturing it, copper strip may also be known as brass strip, bronze strip, red copper strip, or white copper strip. Read More…
Copper StripCopper strips are long, thin planes of the popular non-ferrous metal known as copper. Also known as trim, strips are used in many industrial, commercial and residential settings to change the aesthetic or functional properties of a structure, piece of equipment or finished product.

The manufacturer transforms the ore from its unprocessed, mined state into a purified version for use in numerous industries. Oxide and sulfide ores that contain between 0.5% and 2.0% copper are commonly used to extract copper. Copper producers use different refining methods depending on the type of ore, as well as other economic and environmental factors. Currently, sulfide sources account for around 80% of the world's copper production. Copper processing is a complicated process that requires numerous steps. Let’s look at this process further.
Stage 1: Melting Down Copper
Today, copper is typically melted down in an electric furnace known as an induction furnace where they are better able to reach and monitor the required temperature for melting this ore; copper has a high melting point of 1083°C (1981°F). Induction furnaces are extremely pricey industrial equipment, but they do ensure a level of safety that is not present in foundries that are self-built. Typically, copper is melted down by itself but, occasionally, other materials such as zinc may be added to create a copper alloy.
Stage 2: Laboratory Test
Next, blocks from each batch of copper are sent to a laboratory where they are inspected to guarantee that specific customer requirements and product specifications are met.
Stage 3: Cutting
After each batch is approved, it is formed into a copper strip. The entire copper strip is then placed on a cutting table, and cut off using a cutting wheel saw. Then the copper strip's uneven surface is smoothed using a copper strip surface washing machine, which is advantageous for the copper strip's later-processed surface for smoothness and flatness.
Stage 4: Hot Rolling
Next, the copper strip is heated at a temperature of 1,000 °C (1,832 °F), and then rolled to ensure a uniform thickness and create a more workable material.
Stage 5: Washing With Water
There are still surface impurities after the hot rolling process is applied to each copper block. As a result, it is first subjected to the sealing furnace and then the washing procedure is undertaken in order to prevent the completed product's quality from being impacted. Then, the dark red areas are eliminated by a fine metal brush during washing and the middle red sections on the copper strip's surface are washed away by the acidity in the washing pool.
The copper strip clearly sparkles following this round of treatments. However, there are frequently still red plaques, so it is critical to repeat the washing stage. The washing pool’s acidity is regularly checked during the washing process and acid is added as needed in order to prevent the acid level from being too low and causing insufficient washing.
Stage 6: Rolling the Plate
Finally, the copper strip is heat treated and forged inside a sealing furnace, then processed to go from a rough to a fine material of specified size.
Copper Strip Types
Copper strips come in a variety of thicknesses and diameters. These strips provide numerous advantageous qualities and, as a result, are ideal for a variety of application needs. Let's examine the various types of copper strips produced, the benefits they provide, and where they are utilized.
Bare Copper Strip
Bare copper strip is known for its longer service life, precise engineering, dimensional control, and crack-free bends. While these strips' available widths range from 6 mm (0.23622”) to 359 mm (14.1339”), their thicknesses range from 0.01 mm (0.000393701”) to 60 mm (2.3622”). These strips are frequently found in automatic machines where they are employed primarily for their capacity to enhance production. Due to its conductivity, production facilities use copper strips as raw materials in a variety of equipment including machine parts, generators, transformers, and appliances. These strips are renowned for their ability to resist corrosion and they are frequently used by production businesses that are based in areas with high soil salinity levels. These strips are most frequently used as switch terminals, electrical contacts, electrical conductors, and electrical circuits in such conditions.
Enameled Copper Strips
Enameled copper strips provide many beneficial characteristics including durability, flexibility, tensile strength, and resistance to heat, water, and weather. Due to these traits, enameled copper strips are mostly utilized for insulation. However, their exceptional performance value supports a variety of additional applications. They are most frequently used in a variety of switch gears and oil field transformers. Numerous companies also employ enameled copper strips for binding. These strips are also used to connect a variety of components including electric motor stators, high-voltage motors, and specialized transformers.
Benefits of Copper Strips
They require almost zero maintenance once installed.
Copper strips have a capacity to function even under adverse weather conditions.
Copper strips provide excellent electrical conductivity.
They feature greater toughness and corrosion resistance than other materials.
