Aluminum-Copper alloying solutions engineered for precise copper additions to aluminum. Our portfolio includes AlCu master alloy ingots and copper tablets for aluminum. They are designed for fast melt-in, low dross, and tight composition control. Use them to tune strength, fatigue resistance, and heat performance in wrought and cast grades, including 2xxx and Cu鈥憁icroalloyed 6xxx.
Precipitation hardening: Controlled copper promotes a consistent response during homogenization, solution treatment, and aging. Expect stable yield strength, fatigue life, and temperature performance in sheet, extrusions, and castings.
Clean, fast dissolution: Compared with pure copper, master alloys and tablets melt quickly with reduced oxidation and slag. Stable geometry and optimized surface area support clean melts and shorter furnace time in die casting, rolling, and extrusion.
Tight chemistry and trace control: Each batch is checked by spectral analysis and process audits to verify copper content, low gas pickup, and controlled traces (Fe, Si, Ti, V, B). This consistency supports predictable properties.
Cast ingots allow safe handling and precise dosing in primary and secondary operations. Uniform chemistry and controlled microstructure promote rapid dissolution and good dispersion.
AlCu10 (approx. 10% Cu, Al balance): Enables fine microalloying in 6xxx extrusions and select 5xxx, giving subtle strength gains with limited impact on conductivity. Suited to billet makers and extruders working within narrow property windows.
AlCu50 (approx. 50% Cu, Al balance): A concentrated source for quick composition adjustments in 2xxx sheet and plate or high-strength castings, improving dosing efficiency in large furnaces.
Compact tablets provide defined copper increments with minimal fume and splash. They enhance operator safety and reduce variability in foundry and die casting environments.
Dosing options: Multiple tablet weights support small crucibles through reverberatory furnaces. Moisture-resistant packaging helps maintain stable storage and performance in humid conditions.
Typical impurities and melt behavior: Low Fe, Si, and gas-forming species reduce inclusion and porosity risk. Tablet geometry and binder systems promote rapid dissolution, low slag, and uniform dispersion.
Foundry and die casting: Tablets and master alloys fit standard refining and degassing routines. Controlled addition helps achieve target properties with minimal impact on cycle time.
Extrusion billets and rolling slabs: For 2xxx and microalloyed 6xxx, precise Cu input aligns with homogenization and aging schedules, supporting extrudability, surface quality, and mechanical consistency.
Secondary aluminum melts: Stable dosing compensates for recycled feed variability, restoring tight chemistry while maintaining low oxidation and clean melts.
2xxx series high-strength sheet and plate for aerospace structures, tooling plate, and parts needing heat resistance.
6xxx automotive extrusions where micro-level Cu adjusts aging response, crash performance, and dimensional stability.
High-strength castings and complex geometries that benefit from tailored heat treatment while managing porosity and machinability.
Manufactured under IATF 16949:2016, ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018.
Every batch is validated with spectral analyzers and supplied with a COA for full traceability.
Backed by 100+ patents and participation in drafting standards for aluminum alloy additives.
Production bases: Harbin HQ (new site with three workshops and a provincial R&D center), Cangzhou Plant 1, Cangzhou Plant 2 (A-level R&D institution), and Anhui (designed 120,000 t/yr across master alloys, AlTiB grain refiners, and alloying tablets). These sites provide stable supply and support new composition development.
Distribution: Eight distribution centers and independent warehouses in Fujian, Jiangsu, Chongqing, and Guangdong enable quick delivery of master alloys and tablets. This reduces inventory risk and supports just-in-time operations.
Market presence: We cooperate with leading aluminum groups and export to nearly 40 countries and regions.
Add master alloy or tablets after fluxing and degassing for best dispersion. Adjust the dose to reach the target copper level, considering melt temperature, furnace type, and residence time.
Use refining and degassing flux to improve melt cleanliness before copper addition. Apply grain refiners such as Al鈥慣i鈥態 after dosing to balance grain structure and precipitation response.
Compared with copper shot or rod, AlCu master alloys and tablets melt faster and oxidize less. More uniform distribution supports tighter chemistry, shorter cycles, and predictable heat-treatment outcomes.
This Aluminum-Copper category offers AlCu master alloy ingots (AlCu10, AlCu50) and copper tablets for aluminum to deliver precise copper additions across furnace sizes and process routes, with defined impurity control and moisture-resistant packaging.
