Features of Soft Aluminum Tubes
Flexible and Easy to Bend:
Soft aluminum tubes have low hardness, making them very easy to bend and shape. This flexibility is ideal for complex structures or applications that require frequent bending.
High Ductility:
In the soft (O-temper) condition, these tubes can be easily stretched, flattened, or reshaped without cracking, allowing for versatile forming processes.
Excellent Corrosion Resistance:
Aluminum’s natural oxidation resistance enables soft aluminum tubes to perform well in humid or corrosive environments. However, their wear resistance is slightly lower compared to harder aluminum.
Lightweight:
With a density about one-third that of steel, soft aluminum tubes are highly advantageous for lightweight and portable product designs.
Easy to Process:
Soft aluminum tubes are easy to weld, cut, and finish (such as anodizing or polishing), making them cost-effective and convenient to work with.
Lower Mechanical Strength:
Due to their low strength in the soft condition, these tubes are not suitable for high-pressure or high-load applications.
Process of Bendable Soft Aluminum Tubes
1. Extrusion
Preheated aluminum billets (usually high-purity aluminum alloys) are forced through specialized dies under high pressure. The design of the dies precisely determines the tube’s wall thickness and both inner and outer diameters. This extrusion process forms the initial tubular shape.
2. Annealing
After extrusion, the tubes undergo an annealing process. This controlled heat treatment lowers the hardness of the aluminum, achieving a fully soft (O-temper) state. Annealed tubes are highly ductile, making them easy to bend, form, and weld according to various application requirements.
3. Straightening and Cooling
The extruded and annealed tubes are then cooled and mechanically straightened. This step ensures dimensional stability and makes the tubes easier to handle and further process.
4. Surface Treatment
If required, tubes can undergo further surface treatments such as anodizing, polishing, or powder coating. These processes enhance corrosion resistance, improve aesthetics, and provide additional surface protection.
5. Cutting and Quality Inspection
The tubes are cut to customer-specified lengths with high precision. Each batch is subjected to strict quality control measures, including checks for dimensional accuracy, surface smoothness, and physical/mechanical properties, to ensure compliance with customer and industry standards.

For custom aluminum extrusion projects, we accept a variety of drawing formats, including CAD files, STEP files, and PDF files. However, for extrusions that require additional machining processes, it’s recommended to provide STEP files, as they ensure precise 3D modeling for machining accuracy.
While PDF files are acceptable, converting them into CAD drawings may result in the loss of certain details, requiring us to manually redraw the design, which could increase lead time. For the fastest and most accurate quotation, we recommend providing CAD files (e.g., DWG/DXF) and STEP files to ensure efficient design evaluation and pricing.
Mold fees are an essential part of the custom aluminum extrusion process. Since every order requires a uniquely designed mold tailored to specific requirements, these molds cannot be used for other products. Therefore, the mold fee is necessary and non-negotiable.
We require 100% upfront payment of the mold fee before mold development begins to ensure timely production. However, as a token of appreciation for your support, we offer a refund of the mold fee or equivalent discounts once the order reaches a certain production volume. Specific policies can be discussed based on your order volume and collaboration details.
Our minimum order quantity (MOQ) varies depending on the size of the product. For smaller-sized products, the MOQ is typically 500kg, while for larger-sized products, it is 2 tons.
We will specify the exact MOQ requirements during the quotation process. If your order quantity does not meet the MOQ, we can still arrange production, but an additional fee will be applied to cover mold preheating and production setup time. Rest assured, this extra fee will be reasonable, and we aim to keep it as minimal as possible to ensure smooth cooperation.
Packaging can be customized according to your needs. Options include using protective film or paper to separate and protect the surface, or foam film for additional surface protection. Products can be palletized or packed into cartons, and the quantity per pallet or carton can be specified by the customer.
The standard packaging involves bundling several pieces together with plastic wrap and then securing them onto pallets. Any packaging requirements beyond the standard will be accommodated, and the associated costs will be clearly provided to the customer.
Mold production typically takes 7 days. After the sample is confirmed, producing a full container load of 26 tons generally requires 14 days for extrusion alone. If surface treatment is required, an additional 3 days will be needed. For machining, extra time will be required depending on the complexity and volume of the machining work. The exact additional time for machining will be determined based on the specific processing requirements.
Aluminum profiles are naturally corrosion-resistant due to the formation of a thin, protective oxide layer when exposed to air or water. This oxide layer is stable and self-repairing, meaning that even if the surface is scratched or cut (such as at exposed ends or during processing), the aluminum will not rust or corrode like iron or steel. Instead, the exposed areas will quickly form a new oxide layer, providing continuous protection against further oxidation.
With proper design, installation, and maintenance, aluminum profiles can last for decades, even in challenging environments. For example, untreated aluminum can easily withstand 20-30 years in outdoor applications, while profiles with surface treatments like anodizing or powder coating can last even longer, often exceeding 50 years. This makes aluminum an excellent choice for applications where durability and long-term performance are essential.
The price of aluminum profiles consists of several components: raw material costs, extrusion processing fees, surface treatment fees, machining costs, and additional packaging fees. Among these, the cost of aluminum as a raw material tends to fluctuate frequently, while other fees remain relatively stable. Due to these fluctuations, our quotations are typically valid for 7 days.
Pricing can be structured in different ways depending on the product and requirements. It can be calculated by weight (e.g., cost per ton), by length (e.g., cost per meter), or by piece (e.g., cost per unit). For products involving extensive machining, such as heat sinks, pricing is generally calculated on a per-piece basis to accurately reflect the additional processing costs. This flexible pricing approach ensures the quote is tailored to the specific needs of the customer.
We can manufacture aluminum profiles in compliance with technical requirements that meet European standards (EN), American standards (ASTM/AA), or other standards as specified by the customer. Custom production is tailored to ensure that the profiles meet the specific standard requirements requested.
Our production equipment is designed for the metric system. If the drawings provided are in the imperial system, we will convert them into metric units for production to ensure accuracy.
It is important to note that while we can machine imperial-threaded holes for fasteners, if you require us to supply matching imperial fasteners, they may not always be available in stock. Custom orders for imperial fasteners typically require a large volume for production. Please consider this when planning your project.
