New O-Temper Aluminum

O-Temper Aluminum

O-Temper Aluminum

Temper Designation O “Annealed” applies to wrought products that have undergone a thermal treatment to reduce their mechanical property levels to their minimums. Often described as “dead soft” metal. Annealing reduces strength and hardness to increases the materials ductility, making it softer and more workable. O-temper or annealed aluminum can be cut, shaped and deformed more easily than aluminum that is not annealed. Plus O-temper aluminum is less expensive than aluminum alloys with other tempering, making O-temper aluminum a versatile, cost-efficient option for a variety of applications.

Aluminum is often referred to as a “miracle metal.” Its long list of inherent properties – lightweight, corrosion resistant, easily formed, highly conductive, highly reflective, non-toxic, durable and recyclable – gives manufacturers and designers a wide range of options for product innovation and process improvements. It is often chosen for applications in which weight savings are important because of its high strength-to-weight ratio. Aluminum’s corrosion resistance make it suitable for numerous environments. And many aluminum alloys with O tempering have higher workability than other alloys, allowing them to be drawn, spun, welded or brazed.

O-temper Aluminum for Welders

Online Metals’ expanded O-temper aluminum inventory is great news for welders. A common mistake when designing an aluminum welding project is to disregard O-temper materials and choose the alloy with the highest strength. However when welding, no matter what temper one starts with, the properties in the heat affected zone (HAZ) of the weld will be those of the O-temper annealed material due to the welding operation. Therefore, your design should be based on the annealed properties, not on the strain-hardened properties. Because of this, it usually doesn’t make sense to buy the more expensive strain-hardened tempers for welded fabrications. Designing with and specify the alloy in the O-temper and up-gauge as necessary can help reduce cost and ensure the strength of your welds.

Aluminum Applications

By virtue of its strength and beauty, aluminum has become the cornerstone of buildings, automobiles and much of the technology we rely on. Lightweight, durable and infinitely recyclable, aluminum is an essential element of daily life. As the sustainable material of choice, its applications span from everyday items like fuel-efficient vehicles, smart phones and tablets, laptops, zippers and foil to the wiring in our nation’s power grid, the apex of the Washington Monument and housing the International Space Station. The automotive industry is an excellent example of how the use of aluminum been used to reduce weight and vastly improve energy costs and consumption – making it a more sustainable option over other materials.

For heavy industrial markets, aluminum brings a durable, strong, corrosion-resistant material that is also lightweight and easily formed. Transportation and aerospace companies can create innovative products without sacrificing safety or performance. In consumer applications, manufacturers value aluminum’s lightweight properties for reducing transportation costs and its visual appearance for creating appealing designs. Across all industries, aluminum’s infinite recyclability supports sustainable manufacturing and makes a positive contribution to the nation’s environmental goals.

Aluminum is truly the metal of modern life.
