The Aluminium slugs of different shapes are heat-treated, soft - annealed and the surface tumbled or sand blasted. The slugs are widely used for the manufacturing of aluminum containers or Collapsible Aluminium tubes for cosmetics, pharmaceutical, beverage containers, and many other packaging solutions.
To produce our slugs, we use an aluminum strip of guaranteed purity of at least 99.7% AL, which meets China and international standards.

Difference of PIR Aluminum slug and PCR aluminum slug
Application of aluminum slugs:
Our aluminum slugs can be used to manufacture a variety of end products, such as collapsible tubes, medicine tubes, cosmetic containers, aerosol cans, aluminum bottles, capacitor housings, automotive oil filter housings, marker pen tubes, bottle caps, and more.
Aerosol Cans Aluminium Slug
Aluminium slug for aerosol cans is a key raw material used in the impact extrusion process to manufacture seamless aluminium aerosol containers. These slugs are solid, blank discs made from high-purity aluminium and are critical for forming durable, lightweight, and corrosion-resistant aerosol cans.
Capacitor shell Aluminium slug
Aluminum slugs are essential raw materials for manufacturing capacitor shells, particularly for electrolytic capacitors, which require precision forming, excellent thermal conductivity, and corrosion resistance. These slugs are impact-extruded to form durable, sealed capacitor housings
Aluminum slugs for fuel cells
Aluminum slugs for high pressure nail gun fuel cells etc,Some cordless nail guns use fuel cells with metal slugs (often aluminum ) to generate gas (hydrogen or combustion gases) for driving nails. These systems rely on a chemical reaction (e.g., aluminum + water → hydrogen) to create pressure instead of relying on compressed air or batteries.
Collapsible tube Aluminum Slugs
collapsible tubes (e.g., for toothpaste, cosmetics, pharmaceuticals, and industrial adhesives). These slugs are extruded or impact-formed into seamless tubes with precise dimensions.

Aluminum Slug for Beer Can
Aluminum Slug for Beer Can refers to precision-engineered aluminum blanks used in impact extrusion to manufacture aluminum beer bottles or cans — especially for reusable, resealable aluminum bottles, not the standard drawn & ironed (D&I) aluminum cans 1070 Aluminum Slug for Beer Can is most common.

Aluminum Slug for Beverage Can
Aluminum bottle cans (resealable beverage containers often used for beer, soda, juice, or energy drinks), aluminum slugs are the correct raw material. These slugs are used in impact extrusion to form strong, thick-walled bottle-shaped cans — not the thin-walled standard soda cans made from aluminum coil.
Production methods of aluminum slug
We TMR offers two different production methods for Aluminum Slug: Stamping and Saw Cutting. Each method has its unique process flow to ensure high-quality and high-performance products.
Stamping production process
Smelting:We first melt high-quality aluminum ingots (AA1070 alloy, 99.7% purity) into molten aluminum. The molten aluminum undergoes degassing, refining, and filtration before entering the casting wheel to ensure purity. The use of aluminum ingots, compared to direct use of molten aluminum, offers better performance with fewer impurities, ensuring higher product quality and consistency. The furnace temperature is strictly controlled, and all atmospheric emissions comply with environmental regulations.
Continuous Casting and Rolling: We use a ring-type casting and rolling machine to produce high-quality aluminum strips from molten aluminum. This process not only maintains excellent mechanical properties and consistency in the aluminum material but also enhances deep-drawing capabilities, reducing the risk of cracking after stamping. The casting wheel runs at speeds of up to 7 meters per minute, producing strips with a width of up to 180mm and thickness up to 20mm.
Stamping:High-precision stamping machines are used to process the aluminum strip into Aluminum Slug. We strictly control the dimensions and shapes of each batch, typically using multiple high-speed stamping machines, each equipped with unwinding and straightening machines to ensure no deviation in the strip during the stamping process. Accurate lubrication is applied to improve stamping efficiency. Stamping waste is recycled to ensure the environmental sustainability and efficiency of the production.
Annealing:Annealing is carried out in a box-type annealing furnace at 530°C for approximately 10 hours to ensure uniform internal structure and improve the product's ductility and fatigue resistance. We use a tunnel-type electric heating annealing furnace with a processing time of about 8 hours to ensure each batch of aluminum slugs meets the minimum strength and optimal ductility.
Surface Treatment:Rolling or shot blasting is used to ensure the surface roughness of the aluminum slugs meets the standards for applying cold extrusion lubricants. The rolling treatment is done by placing the slugs into a rotating drum, while shot blasting is done by spraying aluminum shot on the rotating belt. The surface treatment time typically ranges from 12 to 15 minutes, depending on the slug size.
Packaging:The finished aluminum slugs are packaged based on customer requirements. Each batch undergoes strict inspection and weighing before packaging in cardboard boxes, with each box weighing 25kg. These boxes are then placed on wooden pallets, with each pallet holding 45 boxes for a total weight of 1125kg. The products are securely plastic-wrapped for safe export transportation.
Saw cutting production process
Bar Preparation: TMR uses hot-extruded bars or precision drawn bars, made from EN AW-1xxx, EN AW-3xxx, EN AW-5xxx, and EN AW-6xxx series aluminum alloys to ensure consistency in formability and deep-drawing performance.
Precision Saw Cutting:High-productivity, high-quality saw cutting equipment is used to accurately cut the bars to the required thickness and diameter. Especially when using drawn bars, tight tolerances are maintained to meet the strictest quality and technical standards.
Annealing:After cutting, the slugs are annealed according to the customer’s specified annealing procedure to adjust the material's hardness and machinability, ensuring the final product's quality and stability.
Surface Treatment:Methods such as shot blasting or vibration are used to process the surface, ensuring smoothness and consistency of the aluminum slug surface, making it suitable for subsequent processing and applications.
Packaging and Storage:The treated aluminum slugs are packaged and stored to prevent damage during transportation and ensure timely delivery to customers.
