TEN-HIGH Tinned Copper Flat Bar 4mmx25mm 1000mm for High Current

Description

Product Overview

The TEN-HIGH tinned copper flat bar is engineered for demanding electrical applications where performance, durability, and reliability are paramount. Constructed from copper with a purity of 99.9% and coated with a protective tin layer, this flat bar combines the excellent conductivity of copper with the corrosion resistance of tin plating. Measuring 4 mm in thickness, 25 mm in width, and 1000 mm in length, the bar provides a substantial cross‑sectional area that reduces voltage drop and heat generation even under heavy load conditions.

Low resistivity is a key attribute of copper, and the tin‑plated finish further enhances the material’s ability to maintain stable electrical characteristics over time. The flat bar’s geometry offers high bendability, allowing it to be shaped or routed within bus ducts, panels, and other assemblies without compromising structural integrity. This flexibility is especially valuable in custom‑engineered solutions where space constraints and complex routing paths are common.

In addition to its electrical advantages, the product meets rigorous industrial standards for safety and quality. The manufacturing process includes precision extrusion, thorough cleaning, and a uniform tin coating applied under controlled conditions to guarantee consistent thickness and adhesion. Each bar is inspected for dimensional accuracy, surface finish, and electrical performance before shipment, ensuring that customers receive a component that meets or exceeds specifications.

Usage

This tinned copper flat bar is ideally suited for a wide range of high‑current applications across various industries. In power distribution systems, it serves as a bus bar that interconnects transformers, circuit breakers, and switchgear, providing a low‑impedance path for large currents. Its robust construction makes it reliable for both high‑voltage and low‑voltage environments, from industrial plants to renewable energy installations.

Electrical engineers often select this product for use in switch contacts and relay assemblies where rapid current changes occur. The tin‑plated surface reduces contact resistance and minimizes arcing, extending the lifespan of moving parts. In manufacturing settings, the flat bar can be incorporated into motor control centers, panel boards, and automated equipment that demand consistent performance under continuous operation.

Beyond traditional power applications, the bar is valuable in metal smelting and refining processes where conductive pathways must withstand harsh chemical exposure and elevated temperatures. Its corrosion‑resistant coating helps prevent degradation caused by acidic or alkaline environments, ensuring stable operation over extended service periods.

Installation is straightforward: the bar can be cut to length, drilled for mounting, or bent to fit specific conduit layouts. Its dimensions align with standard mounting hardware, reducing the need for custom fittings and accelerating project timelines. Whether used in new construction or retrofitting existing infrastructure, the TEN‑HIGH flat bar delivers the performance engineers expect from premium copper conductors.

FAQ

What is the advantage of a tin‑plated copper bar over bare copper?

The tin coating acts as a protective barrier that prevents oxidation and the formation of copper oxide, which can increase contact resistance. This results in more stable electrical performance, especially in humid or corrosive environments, while retaining the high conductivity of the copper core.

Can the flat bar be cut or bent to custom lengths?

Yes. The material’s high ductility allows it to be cut with standard metal‑cutting tools and bent using conventional pipe‑bending equipment. For precise dimensions, we recommend using a fine‑toothed saw and a calibrated bending jig to maintain the integrity of the tin coating.

Is the tin plating thickness consistent across the product?

Our manufacturing process applies a uniform tin layer that meets industry‑standard thickness specifications (typically 5–10 µm). Each batch is inspected for coating uniformity, ensuring consistent performance throughout the entire length of the bar.

What certifications or standards does this product meet?

The flat bar complies with IEC 60228 for copper conductors and conforms to RoHS directives regarding hazardous substances. Additionally, our quality management system is ISO 9001 certified, guaranteeing that each product adheres to rigorous quality and safety standards.

How does the product perform in high‑temperature applications?

The copper core can tolerate temperatures up to 200 °C without loss of conductivity, while the tin coating remains stable up to approximately 150 °C. For applications exceeding these temperatures, we advise consulting our engineering team to select an appropriate alternative or protective measure.
