Aluminum extrusion is a metal processing process that plastically deforms aluminum bars or aluminum alloys into profiles with specific cross-sectional shapes. This allows for customized shapes. I. Classification of Aluminum Extrusion Its classification is typically based on different dimensions, such as process parameters, product characteristics, die structure, or alloy type, to meet diverse technical requirements and product applications. The following are the most common classification methods. 1. Classification by Alloy: Generally, there are pure aluminum extrusions, aluminum-manganese alloy extrusion, aluminum-magnesium alloy extrusion, etc. 2. Classification by Temperature: Hot extrusion (usually 350-550°C), cold extrusion (≤150°C), and warm extrusion (150-350°C). 3. Classification by Die: Flat die extrusion, conical die extrusion (flat-conical die), split die extrusion, and combination die extrusion. 4. Classification by Product Cross-sectional Shape: Solid profile extrusion, hollow profile extrusion, and tube extrusion.   II. The methods for various extrusion types are similar. The following is an introduction to hot extrusion.   Core Material Preparation: Generally divided into four categories: raw materials, die tools, consumable materials, and post-processing materials (surface treatment, machining, and testing materials). General Extrusion Steps 1. Casting Rod...

What is the difference between aluminum and extruded aluminum? Aluminum is an unprocessed plastic material. Aluminum profiles are products produced by aluminum extrusion process, which have higher strength, unlimited length and strong designability. 1.Aluminum Aluminum is a basic metal material, essentially a raw material, typically obtained through direct mining. Common forms of aluminum include:  Cast Parts commonly used in automotive parts, aerospace, machinery and hardware, consumer electronics (mobile phone/laptop midframes), and heat sink casings. Sheets (Used For Stamping Or Rolling) typically 0.2 to 200mm thick. Common metal cans (both the body and lid) for cola, beer, juice, and the like are made from aluminum sheet. Rods/Wires (Used For Drawing) generally higher in strength, are commonly used to make screws/nuts/bolts, and gears. Castings (Used For Complex Shapes) commonly used in engine blocks/cylinder heads, LED lighting radiators, and bathtub faucet bodies. Thus, aluminum is a raw material that has not undergone specific plastic processing and must undergo further processing to be manufactured into finished products.   2. Extruded Aluminum This is a highly processed aluminum product, produced through an extrusion process. The...

When purchasing high-quality aluminum profiles, we often wonder what type to choose. Actually, there's a lot to learn about aluminum profiles. Below is some helpful information about aluminum profiles, hoping it will help you avoid wasting money. 1. Basic Properties of Aluminum Property​ ​Description​ ​Color​ Silvery-white ​Abundance in Earth’s Crust​ The ​most abundant metal element​ in the Earth's crust (~8.3% by mass). ​Oxide Film & Corrosion Resistance​ Forms a ​thin, protective oxide film​ in moist air, preventing further corrosion. As a result, it may become slightly dull over time when left exposed. ​Relative Density​ 2.7 g/cm³ (lightweight compared to most metals). ​Melting Point​ 660.37°C ​Boiling Point​ 2327°C ​Specific Strength​ High (excellent strength-to-weight ratio). ​Electrical Conductivity​ Good (second only to silver and copper). Widely used in ​high-voltage transmission lines​ due to this property. ​Thermal Conductivity​ Excellent (~3x higher than iron). Often used in ​radiators/heat sinks​ for efficient heat dissipation. ​Reflectivity & Oxidation Resistance​ High reflectivity (e.g., for mirrors or reflective coatings) and strong oxidation resistance (reinforced by its oxide film). 2. Types Profiles: high-quality aluminum profiles, aluminum tubes, aluminum bars, etc....

This is an article about choosing between aluminum profiles and steel. It mainly talks about which is cheaper, aluminum profiles or steel. It introduces the differences and advantages of the two from the perspectives of raw materials, processing, cost, maintenance, etc., so as to help you choose the material that meets your needs and expectations. I hope it can help those in need. Raw Materials The raw materials for aluminum profiles are more expensive than steel. The price of aluminum ingots (approximately 20,000 yuan/ton) is higher than that of ordinary steel (approximately 5,000 yuan/ton). However, the price of high-strength aluminum alloys (such as 7075) is close to that of specialty steel. Processing Costs Aluminum profiles are primarily extruded. Compared to steel rolling, the energy consumption is only one-third of that of steel, and the processing efficiency is much higher than that of steel. Therefore, aluminum profiles are more suitable for high-end customization needs. Overall cost is similar between the two. Transportation Costs Due to the low density of aluminum profiles, they are lighter. In terms of volume, steel is three...
