If you need a 6 × 7 mm Copper strap or switchboard busbar systems, earthing systems, or transformer equipment, accurately choosing the cross-section, purity, and temper condition directly impacts both performance and purchasing costs. This 6 × 7 mm strap is utilized in specialized electrical and grounding applications and is available in various grades, including ETP copper and 6 × 7 oxygen-free copper (OF) strap. Since copper strap pricing is calculated based on weight, the following sections review the weight per meter, technical specifications, and factors affecting the price of the 6 × 7 copper strap so you can more accurately estimate your project requirements. To inquire about the daily price of the 6 × 7 copper strap and place an order by meter or by branch, you can submit your order specifications.

Factors Affecting the Price of 6 × 7 Copper strap

The price of the 6 × 7 copper strap is determined based on weight, technical specifications, and market conditions. For a precise quotation, several key factors must be evaluated simultaneously:

• Daily Copper Price: Copper is the primary raw material for this product, and its price fluctuations directly affect the strap’s rate.
• Actual Product Weight: The nominal dimensions of 6 × 7 mm serve as the basis for calculating the cross-sectional area, but the final weight may vary slightly due to manufacturing tolerances.
• Copper Type: ETP copper strap and 6 × 7 oxygen-free copper (OF) strap differ in composition and manufacturing processes, which can lead to price variations.
• Temper/Hardness Grade: Annealed, half-hard, and hard straps undergo different production processes, and selecting them affects the price.
• Order Quantity: The purchasing volume, number of branches, or required meter length can influence the unit price of the product.
• Supply and Preparation Type: Purchasing by branch, in coils, or cut to specific lengths involves different supply conditions.
• Exchange Rates and Supply Costs: In the Iranian market, currency fluctuations and raw material supply costs can cause price volatility in copper products.

Technical Specifications and Features of 6 × 7 Copper strap

The 6 × 7 copper strap is used in industrial electrical projects, busbar systems, and grounding networks. The 42 square millimeter cross-section of this strap creates a specific weight per meter, which is important when calculating the total copper required for a project. Furthermore, copper’s high conductivity and mechanical properties make this cross-section suitable for manufacturing electrical connections and conductors.

What is the Weight per Meter of 6 × 7 Copper strap?

To calculate the weight, we consider the 6 × 7 mm cross-sectional area over a length of one meter. This calculation yields a specific volume of copper which, factoring in copper’s density, determines the theoretical weight per meter.

• The theoretical weight of each meter of the 6 × 7 strap is approximately 375 grams.

This value is useful for initial order weight estimations. The actual product weight may vary slightly due to manufacturing tolerances, and for bulk orders, the actual weight serves as the basis for calculation.

What is the Current-Carrying Capacity of 6 × 7 Copper strap?

The 42 square millimeter cross-section plays a role in determining the current-carrying capacity of this strap. However, the tolerable current also depends on installation conditions. Ambient temperature, installation method, air circulation, distance from other conductors, and allowable operating temperature alter the current capacity.

In switchboard busbar systems, the allowable current must be determined based on actual installation conditions and project design requirements. Therefore, a fixed amperage cannot be applied to all applications of the 6 × 7 copper strap.

Dimensions, Tolerances, and Supply Methods of 6 × 7 Copper strap

The nominal dimensions of this product are 6 by 7 mm. Dimensional tolerances are critical in industrial orders, especially when the strap must be installed in a confined space or interface with parts and fittings of precise dimensions.

Depending on the supply method, this product can be provided in the length and form required by the project. Before placing an order, it is best to coordinate the required length, installation method, and cutting or packaging preferences with the supplier.

Summary of Specifications to Review When Purchasing:

Precise specifications regarding purity, oxygen content, grade, conductivity, mechanical properties, and product standards are listed in the technical table at the beginning of the page and do not need to be repeated here.

Types of 6 × 7 Copper strap

The 6 × 7 copper strap can be categorized based on purity levels and oxygen content. The type of copper affects its conductivity, mechanical properties, and application. In this classification, oxygen-free copper holds a special place for applications where high purity and conductivity are essential.

6 × 7 Oxygen-Free Copper strap

The 6 × 7 oxygen-free copper strap is produced from copper with a very low oxygen content. OFE Copper (Grade C10200) falls into this category and represents an ideal choice for specialized electrical applications in terms of copper purity and electrical conductivity.

Low oxygen levels reduce the risk of oxide compound formation within the copper structure, helping maintain optimal electrical and thermal properties. For this reason, this type of copper is used in manufacturing conductors, busbars, electrical connections, and certain power equipment.

Grade C10200, with its high conductivity and favorable mechanical properties, makes this product well-suited for industrial busbar systems and electrical equipment.

ETP Copper strap

ETP copper is one of the most common grades of copper for electrical applications and offers high conductivity. This type of copper contains a higher oxygen content in its structure compared to oxygen-free copper and is widely used in manufacturing busbars, conductors, and electrical equipment.

Copper strap with Other Purities and Grades

Depending on production standards and project requirements, copper straps can be supplied with different grades and specifications. Grade selection must be based on the technical requirements, application, operating conditions, and required project standards.
