Alumina Dispersion Strengthened Copper Rods (often referred to as Non-Stick Needles) are high-performance metal materials exhibiting excellent wear, corrosion, and high-temperature resistance. C15760 aluminum oxide copper rods have a standard grain size, softening at 1200 degrees Celsius, and possess a Shore hardness metric between 125 and 240 HB. These materials have an impurity content of 0.01%, demonstrating their stable performance and high purity.

Alumina copper rods are also called Aluminum oxide copper rods and have various applications in the electronics and machinery industries. Alumina copper rods are highly composite materials that industrial sectors are able to use, and they amalgamate the corrosion and wear resistance of Alumina with the superior conductivity of Copper. Such materials are used in the aerospace, electronics, and precision machining industries where the requirements of sustenance and high strength are critical.

C15760 aluminum oxide copper rod is considered to be one of the superior quality copper-based composites with the matrix of copper (Cu) and aluminum oxide (Al2O3) able to withstand dispersion strengthening. Prepared through mechanical alloying or internal oxidation processes, it combines high conductivity, high strength, high-temperature resistance, and excellent wear resistance, and is considered one of the representatives of "high-strength functional copper alloys." This material is widely used in power electronics, high-temperature welding, precision molds, and other fields, especially suitable for demanding working conditions that require both conductivity and mechanical performance.

Chemical Composition

The typical composition of C15760 aluminum oxide copper is as follows:

Copper (Cu): ≥99.0% (matrix, maintaining electrical and thermal conductivity).

Aluminum oxide (Al2O3): 0.2%~0.8% (dispersed distribution, improving hardness and resistance to softening).

Trace additive elements: May contain small amounts of nickel (Ni), iron (Fe), etc., used to optimize processing performance, total content <0.5%.

Physical and Mechanical Properties

Electrical conductivity: Conductivity of 285% IACS, close to that of pure copper, superior to most reinforced copper alloys.

Hardness: Room temperature hardness can reach HRB 90~100, significantly improved wear resistance.

Tensile strength: ≥550 MPa, strength retention rate >70% at high temperatures (500°C).

Softening temperature: ≥800°C, extremely strong resistance to high-temperature softening.

Coefficient of thermal expansion: 16.8×10⁻⁶/°C (20~400°C), good compatibility with ceramic materials.
