Al 7075 powder

Al 7075 powder is a high-strength aluminum alloy composed primarily of aluminum, zinc, copper, and small amounts of magnesium and chromium. It is renowned for its impressive mechanical properties, making it an ideal choice for applications that require strength, durability, and lightweight characteristics. Al 7075 powder is typically produced through a process called atomization, where molten aluminum is sprayed and solidified into fine powder particles.

Overview of Al 7075 Powder

Al 7075 is one of the highest strength 7000 series aluminum alloys, offering strength superior to many steels. Zinc is the main alloying addition while magnesium imparts strength through precipitation hardening.

Key properties of Al 7075 powder include:

Exceptionally high tensile and yield strength

High hardness and good fatigue strength

Good toughness and moderate ductility

Excellent finishing characteristics

High corrosion resistance

Available in range of powder sizes and shapes

Al 7075 powder is ideal for high-performance aerospace and defense components needing the optimal combination of strength, hardness, fatigue resistance, and moderate weldability.

Production Method for Al 7075 Powder

Commercial production methods for Al 7075 powder include:

Gas Atomization – Molten alloy stream disintegrated by inert gas jets into fine spherical powder particles with controlled size distribution.

Water Atomization – High pressure water jet used to produce fine Al 7075 powders with irregular shape. Lower cost but higher oxygen pickup.

Mechanical Alloying – Ball milling a blend of aluminum and alloying element powders followed by cold compaction and sintering.

Gas atomization offers superior control over powder characteristics like particle size, shape and microstructure.

Applications of Al 7075 Powder

Additive Manufacturing – Used in selective laser melting, direct metal laser sintering to produce complex, lightweight aerospace and defense parts.

Metal Injection Molding – To manufacture small intricate components with high strength and moderate corrosion resistance.

Powder Metallurgy – Press and sinter process to create high-performance automotive parts and machinery components.

Thermal Spraying – Wire arc spraying to deposit very hard and wear resistant Al 7075 coatings.

Pyrotechnics – Added as fuel constituent in pyrotechnic compositions due to its high reactivity.

Welding Filler – Used as filler wire providing weld strength but limited weldability.

Specifications of Al 7075 Powder

Al 7075 powder is available in various size ranges, shapes, grades and purity levels:

Particle Size: From 10-45 microns for AM methods, up to 120 microns for thermal spray processes.

Storage and Handling of Al 7075 Powder

Al 7075 reactive alloy powder must be handled with care to prevent:

Oxidation and reaction with moisture

Dust explosion hazards from fine powder

Inhalation related health problems

Safety practices recommended by supplier should be followed

Inert gas blanketing, proper grounding, ventilation, and PPE should be utilized for safe handling.

Testing and Characterization Methods

Key test methods used for Al 7075 powder include:

Chemical composition analysis using OES or XRF

Particle size distribution as per ASTM B822 standard

Morphology analysis through SEM

Powder flow rate using Hall flowmeter

Density measurement by helium pycnometry

Impurities testing by ICP-MS

Microstructure examination by X-ray diffraction

These tests ensure the powder meets the required chemical, physical, and microstructural characteristics for the specific application.
