Polvo de aluminio 7075

Imagine a material that combines the lightness of aluminum with the impressive strength of steel. That’s the magic of 7075 aluminum powder, a game-changer in the world of additive manufacturing and beyond. But what exactly makes this powder so special? Buckle up, because we’re diving deep into its properties, applications, and why it might be the perfect fit for your next project.

Composition and Characteristics of 7075 Aluminum Powder

7075 aluminum powder isn’t your average aluminum shavings. It’s a meticulously crafted alloy, meaning it’s not pure aluminum but a blend of aluminum with other elements to enhance its properties. The key players in this alloy are:

• Zinc (5.6 – 6.1%): Acts as a strengthening agent, making the powder significantly stronger than pure aluminum.
• Magnesium (2.1 – 2.5%): Improves corrosion resistance and workability.
• Copper (1.2 – 1.6%): Contributes to strength and hardness.
• Trace elements: Silicon, iron, manganese, and others play supporting roles in fine-tuning the powder’s characteristics.

This unique blend results in a powder with a remarkable set of properties:

• Alta resistencia: Compared to pure aluminum, 7075 powder boasts significantly higher strength, making it ideal for applications demanding structural integrity.
• Ligero: Just like its aluminum base, 70.75 powder remains lightweight, offering a fantastic strength-to-weight ratio.
• Buena resistencia a la corrosión: The presence of magnesium enhances the powder’s resistance to corrosion, making it suitable for various environments.
• Excellent Machinability: The powder can be readily machined after the 3D printing process, allowing for precise finishing touches.
• Soldabilidad: Joining components made from 7075 powder through welding is achievable.

But wait, there’s more! The magic extends beyond the basic composition. 7075 aluminum powder comes in various forms, each with its own advantages:
