Aluminum

Aluminum is a lightweight metallic element with the chemical formula Al and CAS number 7429-90-5. It has a molecular weight of 26.981538 g/mol and is classified as a flammable solid that reacts with water. This silvery-white metal is the third most abundant element in Earth's crust and exhibits excellent corrosion resistance due to its natural oxide layer. Aluminum is highly valued for its low density, good electrical conductivity, and recyclability properties.

Aluminum is a silvery-white, lightweight metal with a density of 2.70 g/cm³ and melting point of 660°C. It is odorless and exhibits excellent thermal and electrical conductivity. The metal is insoluble in water but reacts slowly with it, especially when finely divided or heated. Aluminum readily forms a protective oxide layer when exposed to air, providing natural corrosion resistance. It is malleable, ductile, and can be easily machined, welded, and formed.

Aluminum is used extensively across multiple industries due to its versatile properties. Primary applications include aerospace and automotive manufacturing for lightweight components, construction materials like window frames and roofing, packaging industry for cans and foils, and electrical applications for conductors and heat sinks. It's also essential in chemical processing, powder metallurgy, and as a reducing agent in metallurgical processes. The metal serves in marine applications, decorative purposes, and renewable energy technologies.

Aluminum requires careful handling as it's classified as a flammable solid (Flam. Sol. 1) and water-reactive material (Water-react. 2). Wear appropriate PPE including safety glasses, gloves, and protective clothing. Avoid generating dust clouds and prevent contact with water, acids, or alkalis. Ensure adequate ventilation in work areas and use non-sparking tools. Keep away from ignition sources, heat, and incompatible materials. Ground equipment properly and maintain good housekeeping to prevent dust accumulation.

Aluminum must be stored in a cool, dry place away from moisture and incompatible materials. Keep containers tightly closed and protect from water, acids, alkalis, and strong oxidizing agents. Store away from heat sources and ignition sources due to its flammable classification. Ensure adequate ventilation in storage areas and maintain temperatures below 40°C when possible. Separate from reactive materials and use appropriate grounding for metal containers to prevent static electricity buildup.

Aluminum contact typically poses minimal immediate health risks, but proper first aid is important. For skin contact, brush off particles gently and wash with soap and water. If eye contact occurs, flush immediately with clean water for at least 15 minutes and seek medical attention if irritation persists. In case of inhalation of aluminum dust, move to fresh air immediately. For ingestion, rinse mouth and drink water. Seek medical advice if symptoms develop or large amounts are involved.

Aluminum disposal should follow local and national waste regulations as it's classified as hazardous waste due to its reactive properties. Avoid disposal with regular waste or down drains. Recycle through authorized metal recyclers when possible, as aluminum is highly recyclable. For contaminated or fine aluminum powder, contact licensed hazardous waste disposal companies. Ensure containers are properly labeled and segregated from incompatible materials during disposal. Consult local environmental authorities for specific requirements.

Aluminum is classified under ADR Class 4.1 (Flammable Solids), Packing Group III, requiring specific transport protocols. Use UN-approved packaging and proper hazard labels including GHS02 pictogram. Vehicles must carry appropriate fire extinguishers and emergency equipment. Drivers need ADR certification for hazardous materials transport. Segregate from incompatible materials like oxidizers and water-reactive substances. Ensure proper documentation including transport documents and emergency response information throughout the journey.

Aluminum is regulated under several European frameworks including CLP Regulation for classification and labeling, requiring 'Danger' signal word and GHS02 pictogram. It falls under REACH registration requirements and ADR transport regulations as Class 4.1 material. While not currently listed as SVHC (Substance of Very High Concern), it must comply with occupational exposure limits and workplace safety regulations. Industrial users must implement proper risk management measures and safety data sheet requirements.
