Available surface treatments for 1070 aluminum slug

To ensure better adhesion of lubricants or oils, improving stamping and forming efficiency while meeting aesthetic requirements, we offer the following professional surface treatment services.

Mill Finish
The aluminum slug is untreated, maintaining its original rolled state. The surface is smooth but not glossy.
Tumbling
The aluminum slug is tumbled with abrasives in a drum, effectively removing surface burrs and oxide layers, while increasing surface roughness.
Shot Peening
5083 aluminum alloy has strong corrosion resistance, can withstand extremely low temperature, and is suitable for application and low -temperature storage tanks in the ocean.
Sandblasting
The aluminum slug surface is cleaned using high-speed sand blasting, removing oxide layers and impurities, while increasing surface roughness.
Anodizing
An oxide film is formed on the surface of the aluminum slug through an electrochemical process, enhancing corrosion resistance and improving aesthetics.
Polishing
The surface of the aluminum slug is mechanically or chemically polished to achieve a mirror-like finish.

Packaging of 1070 aluminum slug

The aluminum slugs are conveyed from the hopper via a conveyor belt into an automated packaging line.
The aluminum slugs are transported to the packaging area and fall into cardboard boxes until they reach a weight of 25 kg.
Each box is precisely weighed to ensure the net weight meets the required specifications.
Clear customer information and product identification codes are labeled on each box.
Every 40 boxes are neatly placed on a wooden pallet, with each pallet weighing a total of 1, 000 kg.
The pallet is wrapped in plastic film to protect the products from moisture and contamination, making it ideal for export shipping.
Clear labels are applied to the outside of the packaging, including product numbers, quality information, customer details, and any other necessary markings for easy identification and management.
Packaging methods can be adjusted according to customer requirements, such as using special-sized boxes or pallets to meet specific shipping and storage needs.

Packaging

Manufacturing of 1070 aluminum slug

Continuous casting and rolling - stamping process

High-purity aluminum ingots (such as 1070 aluminum, purity 99.7%) are melted and purified to ensure the quality of the aluminum melt.
The aluminum melt is cast into narrow or thin strips using the continuous casting process.
The cast strip is then hot-rolled and cold-rolled to the required thickness as per customer specifications.
Using automated stamping machines (120-315 tons), aluminum slugs are stamped from the cold-rolled coil at speeds of up to 300 strokes per minute.
The aluminum slugs are controlled-annealed in a furnace to adjust their hardness (Brinell hardness 16-21 HB).
Surface treatments such as sandblasting, tumbling, or vibration are applied to remove oxide layers, improve lubricant adhesion, and enhance surface smoothness.
Strict quality control is conducted throughout the process to ensure that dimensions, hardness, and surface quality meet standards, with customized packaging according to customer requirements.

The continuous casting and rolling - stamping process is ideal for producing standardized, high-volume thin aluminum slugs, offering high efficiency and low cost.

Saw cutting aluminum slug

After melting high-purity aluminum, it is cast into aluminum rods with appropriate diameters using molds.
A high-precision saw cutting machine is used to cut the aluminum rods into aluminum slugs that meet customer requirements, with flexible diameter and thickness ranges.
The saw-cut aluminum slugs are annealed to adjust hardness and mechanical properties.
Surface treatments such as sandblasting, vibration, or tumbling are selected to improve surface quality and lubricant adhesion.
After inspection, the products are packaged and delivered.

The saw cutting process is suitable for producing non-standard thick aluminum slugs or high-end products, offering greater flexibility.

Powerful production capacity - production machinery

The aluminum slug production process involves the use of aluminum melting furnaces, holding furnaces, automatic continuous casting machines, hot and cold rolling mills, automated stamping machines, annealing furnaces, aluminum slug vibrators, and inspection lines.
