Copper Flat Bar 2PCS 1/16″ x 0.4″ x 8″ 99.9% Pure MTJSWXSY Solid Bar

Description

Product Overview

The 2PCS Copper Flat Bar set from MTJSWXSY is engineered to meet the demanding requirements of both amateur makers and seasoned industrial technicians. Each bar measures precisely 1/16 inch (approximately 1.5 mm) in thickness, 0.4 inch (about 10 mm) in width, and extends 8 inches (203 mm) in length, providing a compact yet substantial piece of material for a wide range of applications. Crafted from 99.9% pure copper, the bars exhibit exceptional electrical conductivity, thermal performance, and corrosion resistance, making them suitable for high‑frequency circuits, power distribution components, and environments where longevity is essential. The solid C110 grade ensures a uniform grain structure that enhances ductility, allowing the material to be bent, formed, and shaped without cracking. In addition, the surface finish is meticulously polished to a bright, mirror‑like sheen, eliminating burrs and sharp edges that could compromise safety or interfere with precise machining operations. The package dimensions of 8.15 × 0.79 × 0.16 inches and a lightweight of 1.94 oz per set make storage and handling straightforward, while the inclusion of two identical bars offers redundancy for projects that require multiple identical components or for backup during prototyping phases. This product has earned a solid reputation within the industrial and scientific community, reflected in its ranking as #18 in the Copper Bars subcategory and a customer rating of 4.5 stars from 22 verified purchasers.

Usage

Designed with versatility in mind, the copper flat bars excel in a multitude of real‑world scenarios. For electrical engineers, the high purity copper provides low resistance pathways ideal for custom bus bars, grounding straps, and prototype circuit boards where signal integrity is paramount. In the realm of metalworking and fabrication, the bars can be easily cut with standard hacksaws, shears, or CNC equipment, and they respond well to drilling, tapping, and threading, enabling the creation of bespoke connectors, brackets, and mounting hardware. Hobbyists engaged in DIY electronics, jewelry making, or knife crafting will appreciate the ease with which the material can be shaped using hand tools, sanders, or polishing wheels, while retaining its structural strength and aesthetic appeal. The bars also serve as an excellent substrate for brazing and welding operations; the high copper content promotes strong metallurgical bonds without the need for excessive filler material, reducing waste and simplifying post‑process cleanup. Maintenance professionals can employ the bars for repair tasks on electrical appliances, switches, and power distribution equipment, taking advantage of the material’s ability to dissipate heat efficiently and resist oxidation over prolonged service life. Whether used in a home workshop, a university laboratory, or a commercial manufacturing floor, the copper flat bars provide a reliable foundation for projects that demand both performance and durability.

FAQ

What is the difference between this copper flat bar and lower‑grade copper alloys?

Our bars are made from C110 grade copper with 99.9% purity, which means they have higher electrical conductivity, better corrosion resistance, and a more uniform grain structure than lower‑grade alloys that may contain additional elements such as zinc or tin. This results in smoother machining, more reliable performance in high‑frequency applications, and longer service life.

Can I weld or braze these bars without additional filler material?

Yes, the high copper content allows for strong metallurgical bonds using standard welding or brazing techniques. For most applications, a small amount of filler is sufficient, but the bars can also be joined directly with proper heat control, reducing material costs and simplifying the assembly process.

What tools are recommended for cutting and drilling the bars?

Standard hacksaws, metal shears, or CNC milling machines work well for cutting. For drilling, use carbide‑tipped drill bits and maintain a moderate feed rate to avoid overheating. Lubricants such as cutting oil can improve finish quality and extend tool life.

Are the bars suitable for outdoor or marine environments?

The 99.9% pure copper offers excellent corrosion resistance, making the bars suitable for outdoor installations and marine applications where exposure to moisture and salt is common. However, for extreme marine conditions, applying a protective coating can further enhance durability.

How do I verify the dimensions and purity of the bars upon receipt?

Each package includes a detailed specification sheet that lists the exact dimensions and purity level. You can use a calibrated micrometer or caliper to confirm thickness, width, and length, and a portable X‑ray fluorescence (XRF) analyzer can be employed to verify copper purity if required for quality assurance.
