In the world of precision aluminum extrusions, the choice of alloy is paramount to the success of any project. Among the versatile family of aluminum alloys, 6063 stands out as a premier choice for applications demanding an exceptional balance of extrudability, strength, and aesthetic appeal. This technical profile delves into the specific composition, mechanical properties, and diverse applications of our premium 6063 Aluminum Rod, engineered to be the ideal raw material for your next innovation.
1. Precise Chemical Composition: The Foundation of Performance
The superior characteristics of 6063 aluminum are a direct result of its meticulously controlled chemical composition. As a member of the 6000 series (Al-Mg-Si) alloys, its properties are derived from the formation of Magnesium Silicide (Mg₂Si) precipitates during heat treatment. The standard composition is as follows:
· Aluminum (Al): Remainder (Approximately 98.9%)
· Magnesium (Mg): 0.45% – 0.9%
· Silicon (Si): 0.2% – 0.6%
· Iron (Fe): ≤ 0.35%
· Copper (Cu): ≤ 0.10%
· Manganese (Mn): ≤ 0.10%
· Chromium (Cr): ≤ 0.10%
· Zinc (Zn): ≤ 0.10%
· Titanium (Ti): ≤ 0.10%
· Others (Each): ≤ 0.05%
2. Engineered Mechanical and Physical Properties
6063 aluminum is renowned for its excellent mechanical properties, which are fully realized through controlled thermal processing, primarily the T5 and T6 tempers.
Mechanical Properties (Typical Values):
· Tensile Strength: ≥27 ksi (≥186 MPa) (T5), ≥35 ksi (≥241 MPa) (T6)
· Yield Strength (0.2% Offset): ≥21 ksi (145 MPa) (T5). ≥31 ksi (≥214 MPa) (T6)
· Elongation: ≥8% (T5). ≥10% (T6)
· Shear Strength: Approximately 18 ksi (124 MPa)
· Hardness (Brinell): 60 HB (T5).75 HB (T6)
Physical and Functional Properties:
· Excellent Extrudability: 6063 is the benchmark for extrudable alloys. It allows for the production of complex, thin-walled, and intricate profiles with smooth surfaces and tight dimensional tolerances. This results in high production efficiency and lower per-part costs.
· Superb Corrosion Resistance: Its low copper content grants it very good resistance to atmospheric corrosion, making it suitable for both indoor and outdoor applications without requiring heavy protective coatings.
· High Surface Finish Quality: The alloy responds exceptionally well to anodizing. It produces a clear, bright, and durable anodic layer that enhances both appearance and corrosion resistance. It is also ideal for painting and powder coating.
· Good Machinability: While not a free-machining alloy like 2011 or 6061, 6063 offers fair machinability. It can be readily turned, milled, and drilled to create final components, especially when using proper tool geometries and coolants.
· Moderate Strength-to-Weight Ratio: It provides a favorable combination of lightweight properties and sufficient structural integrity for many non-load-critical applications.
· Weldability: 6063 aluminum exhibits good weldability using common techniques such as Tungsten Inert Gas (TIG) and Metal Inert Gas (MIG) welding.
3. Extensive Application Scope: From Architecture to Automation
The unique property profile of 6063 aluminum rod makes it an indispensable material across a vast spectrum of industries. Our clients utilize it as the foundational stock for custom extrusions and precision machining.
Architectural and Construction Applications
This is the primary domain for 6063.Its aesthetic quality and corrosion resistance make it perfect for:
· Window and Door Frames: Providing structural stability and a superior finish for residential and commercial buildings.
· Curtain Walling and Structural Glazing: Forming the mullions and transoms of modern building facades.
· Roofing Systems and Trim: Used in gutters, downpipes, and decorative architectural elements.
· Handrails and Balustrades: Combining safety with a sleek, modern appearance.
Automotive and Transportation
The lightweight nature of 6063 contributes to improved fuel efficiency and design flexibility.
· Radiator Enclosures and Heat Exchangers: Leveraging its thermal conductivity.
· Trim and Decorative Mouldings: Both interior and exterior applications.
· Chassis and Framework Components: For trailers, recreational vehicles (RVs), and specialized transportation equipment.
· Aerospace Ducting and Interior Components: Where weight savings are critical.
Electrical and Electronics
Its excellent conductivity and formability are key assets.
· Heat Sinks: This is a major application. 6063 is the preferred material for extruded heat sinks in computers, LED lighting, and power electronics due to its optimal thermal conductivity (~209 W/m·K) and ease of creating complex fin designs.
· Conduits and Bus Bar Housings: Providing protective and structural enclosures.
Industrial and Consumer Durables
· Furniture Frameworks: For modern, lightweight, and durable indoor and outdoor furniture.
· Machinery Guards and Framing Systems: Such as T-slot aluminum framing (e.g., 80/20, Bosch Rexroth profiles) used for building custom workstations, enclosures, and automation cells.
· Sporting Goods: Used in the frames of high-end bicycles, camping equipment, and hiking poles.
