Brand 3003 H14 External Diameter 19.5mm Radiator Extruded Aluminum Tube Cold-drawn Aluminum Tube

Let me introduce the main differences between cold drawn and hot extruded aluminum tubes.

1, Our process for crafting cold drawn aluminum pipes involves gradually reducing each metal bar's cross-section while stretching it out - eventually reaching the ultimate desired size. Hot extrusion tubes are made by shaping metal bars through heating them up and pushing them through an extruder.

2, Cold drawn aluminum pipes feature a smooth finish, saving you from extra surface treatments. Hot extruded pipes, however, do have clear extrusion traces that necessitate some special detouring for defective removal.

3, Performance Highlights:

(1) Strength-wise: Cold drawn aluminium pipes offer greater strength yet less flexibility than their hot extruded counterparts, who boast good toughness and flexibility.

(2) In terms of productivity: Cold drawn aluminum tubes offer an easy route for shaping through machining with deeper drawings and pressing possible. On the other hand, hot extruded pipes have limited versatility, suitable mainly for simpler processes like cutting and drilling.

(3) Regarding corrosion resistance benefits: The cold drawn aluminum pipe boasts a sleek, burr-free surface with superior grain size, affording exceptional corrosion resistance. Conversely, hot extruded pipe surfaces exhibit distinct extrusion marks that could potentially form burrs and lessen its resistance against corrosion.

4, Application Scope: Our carefully crafted cold drawn aluminum tubes excel at crafting intricate instrumentation and equipment elements, automobile parts, electronic goods, and more. Hot extruded pipes, on the hand, are adept at producing complex parts, cold-working components, energy efficient door and window systems. As you've gleaned thus far, the production methods, surface finish, performance attributes, and various other features differentiate our cold drawn and hot extruded aluminum tubes. We recommend selecting the appropriate tube material considering your precise needs for optimal outcomes.

Compared to standard aluminum alloy pipes, our cold drawn aluminum alloy square pipes offer these benefits:

1. Enhanced mechanical prowess. Our cold drawn aluminum alloy square tubes score high in terms of yield strength, tensile strength, hardness and are built to endure significant pressure and tension.

2. Impressive anti-corrosion prowess. Each cold drawn aluminum alloy square tube offers a smooth and flat surface for optimal corrosion resistance, resisting rust and corrosion with ease.

3. Superior manufacturing protocol. Our cold drawn aluminum alloy square tube is crafted through the gentle art of cold drawing, boasting a sleek, flat surface, impeccable precision, and resilience against deformation.
To sum up, our cold-drawn alloys are top-tier lightweight, high-strength materials ideal for demanding environments like aerospace, auto production, or construction engineering.

Applications:

While extruded aluminum is extremely common in a wide range of applications, it is not suitable for everything. Any requirement for elevated properties may turn toward cold finished product as raw material. Aerospace and defense products requiring high strength often specify cold finished bar, as well as a host of automotive applications.
