Finishing Options For Extruded Parts
As the machined or deburring
The machined or deburring finish is the standard finish where unwanted attach chips are removed with deburring tools, and sharp edges are chamfered to smooth the surface (3.2 μm).
Bead Blasted
Bead blasting produces a matte texture, removing all the marks of machining tools. It applies to ABS, Aluminum, Brass, Stainless Steel, and Steel parts.
Anodizing
Anodizing involves adding an aluminum oxide coating to aluminum and its alloys. The layers, which come in various colors, increase strength and shield the surface from corrosion.
Powder coating
Powder coating is the electrostatically applying of dry powder to the surface. It produces a thin layer providing excellent resistance to wear, corrosion, and abrasion.
Polishing
Physical rubbing of a metal surface to create a shiny surface is called a polishing surface finish. It increases the reflectivity and does not affect the dimensional stability of parts.
Brushing
Brushing is achieved by applying an abrasive brush to the metal surface, which produces a unidirectional satin finish. And it is not recommended for highly corrosive materials.
Smooth machining
Smooth machining is done by controlling the machining process, such as feed rate & cutting speed. It minimizes the tool marks and risk of corrosion.
Black-Oxide
Black oxide finish reduces surface reflectivity and offers mild corrosion protection. It involves adding a thin layer of magnetite to the surface.
Electro-less Nickel Plating
A thin layer of Nickel is created on the surface from a nickel-containing solution without electrolysis. Electro-less nickel plating provides a shiny appearance, excellent hardness, abrasive, wear, and corrosion-resistance to the substrate material.
Alodine
Provides excellent corrosion resistance property to the aluminum parts with greenish-gold color. It is the low-cost and quick surface finishing approach.
Electroplating
Electroplating increases the hardness of the steel &aluminum parts. It offers excellent corrosion, wears, and abrasion resistance.
Nickel plating
Make the parts super resistive to corrosion. It enhances mechanical strength, hardness, wear resistance, lubricity, and ductility. Nickel plating is applicable in different materials, including Steel, aluminum, copper, and brass.
Passivation
Enhance the appearance and functionality of the parts. After Passivation, parts of Steel and its alloys become super resistive from corrosion.
Yellow Chromate conversion coating
A shiny appearance with goldish color provides excellent corrosion resistance. It is applied on the surface of aluminum, magnesium, and their alloys. A layer of chromate also enhances the conductivity of parts
PTFE (Teflon) Coating
The Teflon layer on the parts offers excellent corrosion resistance, water resistance, and non-stickiness with a non-reactive surface.
Fine machining
The higher-precision machines produce delicate machining surfaces by utilizing sharper tools and regulating feed rate and cutting speed. Surface roughness up to Ra 0.8 μm can be maintained with smooth machining.
Laser Cladding
Provides excellent corrosion, wear, and abrasion resistance. Laser Cladding is also effective for treating minor surface imperfections such as cavities, tiny cracks, and rust damage.
Sanding
Provides a random, non-linear texture with a shiny, high gloss finish. However, it might be unable to create sharp corners and pockets

Technology Overview
What is Aluminum Extrusion?
Aluminum extrusion shapes aluminum by pushing it through a specific mold or die. This results in a long piece with a continuous and, at times, intricate cross-sectional design. Imagine the process of making different pasta shapes with dough: pressure pushes the dough through a mold, and its shape changes based on the mold used. However, aluminum isn’t as soft as dough, so high hydraulic pressure, and sometimes heat, is needed to shape it.
How Does Aluminum Extrusion Work?
Aluminum extrusion is executed using either hot or cold methods. Hot extrusion facilitates the molding of larger aluminum amounts quickly with less pressure. Cold extrusion, however, results in mechanically refined parts with an excellent surface finish and oxidation resistance.
Hot Extrusion Process:
- Aluminum billets are sized accordingly.
- These billets are heated between 300°C and 600°C, softening the metal without melting it.
- Hydraulic-powered ram pushes the heated billets into either a standard or custom die. This requires immense pressure, approximately 10,000,000 pounds.
- Post-extrusion, the shapes are cooled and then cut based on customer requirements. Additional heat treatment can be applied for further aluminum hardening.
Cold Extrusion Process:
- Aluminum billets are prepared and cleaned, ensuring no contaminants that might affect the process.
- Without pre-heating, billets are introduced to the die.
- A hydraulic-powered ram exerts high pressure to push the billets through the die, achieving the desired shapes. This method relies on the aluminum’s ductility at room temperature.
- As no heat is applied, the resulting extrusions have a fine grain structure, increased mechanical properties, and a smooth surface finish.
- Extruded parts are then cut to specific lengths as per customer requirements and may undergo further treatments or finishing processes if necessary.

FAQ
General FAQ:
What is aluminum extrusion?
Aluminum extrusion is a process used to transform aluminum alloy into objects with a definitive cross-sectional profile for a wide range of uses.
Why choose aluminum for extrusion?
Aluminum is lightweight, strong, and corrosion-resistant, making it an ideal choice for various applications.
How long does the aluminum extrusion process typically take?
The duration depends on the complexity and volume of the project, but standard extrusions generally have shorter lead times than custom designs.
Is there a minimum order quantity for aluminum extrusion?
This varies based on the service provider. Some cater to smaller, bespoke projects, while others might have a minimum order requirement for cost-effectiveness.
Technical FAQ:
How do hot and cold extrusion differ?
Hot extrusion involves heating the aluminum before forcing it through a die, making it easier to shape. Cold extrusion pushes the aluminum through the die at room temperature, resulting in a finer grain structure and increased mechanical properties.
What alloys are best for aluminum extrusion?
Commonly used alloys include 6061, 6063, and 7075, but the best alloy depends on the specific application and performance requirements.
