錨點 1

At Pinjaya, we believe sustainability is more than a competitive edge—it is our responsibility in the face of climate change. By choosing 100% recycled aluminum, our customers achieve up to 98% lower carbon emissions compared to the global average of primary aluminum production—setting a new benchmark for low-carbon materials.

Not only do we outperform traditional recycled aluminum producers, but we also empower our partners to meet their sustainability goals and respond to the growing demand from consumers who care deeply about climate impact.

With Pinjaya, every product you create carries a lighter footprint and a stronger commitment to a sustainable future.

Sustainable Aluminum Recycling at Pinjaya.

Recycling and remelting secondary aluminum requires only 5% of the energy needed to produce primary aluminum from bauxite ore. As an infinitely recyclable metal, aluminum can be recovered and reused without degradation in quality.

Pinjaya, through its procurement office in the United Kingdom, sources production scrap, turnings, and offcuts from leading European aluminum processors. These include 7050 aerospace-grade scrap from Airbus manufacturing facilities, 6063 aluminum scrap from architectural door and window producers, and ADC12 automotive die-casting scrap. Such materials are recycled and remelted into high-quality aluminum feedstock, enabling an annual recycling capacity of approximately 40,000 tons.

Each ton of recycled aluminum contributes to avoiding the extraction of 6 tons of bauxite and reduces 9 tons of CO₂ emissions. In total, Pinjaya’s recycling operations achieve an annual reduction of around 360,000 tons of carbon emissions—equivalent to the carbon absorption capacity of 935 Da’an Forest Parks in Taipei.

Introduction to Recycled Aluminum

Recycling Aluminum Ingots
Aluminum alloy ingots have a density of only 2.6–2.7, making them not only lightweight but also highly corrosion-resistant. They are widely used in automobiles, motorcycles, industrial machinery, pneumatic tools, precision equipment, computer and communication devices, as well as household products.

Secondary aluminum alloy ingots are produced by recycling discarded aluminum products, which are remelted and reused, or blended with primary aluminum according to international standards or specific requirements. Various alloying elements are added to meet different specifications, with the purpose of improving the casting, chemical, and physical properties of pure aluminum.

As global resources become increasingly scarce, aluminum’s high recyclability makes the use of secondary aluminum alloy ingots both energy-efficient and environmentally friendly, forming a sustainable recycling chain. This makes secondary aluminum not only an eco-conscious choice, but also an economically sound one.

Aluminum Ingots Portfolio

• ADC 12%

• HD-2 & HD-4

• AC2B

• A.380

• AC8A

• 6063

• A.356

• Taint Tabor

• ADC 6

• Other customized aluminum alloys

Recycled aluminum products

• 7050 (aerospace alloy) → High-strength aluminum, usually comes from aerospace parts, thick plates, or precision components. Scrap often looks like chunky blocks or machined offcuts, dull silver, sometimes with machining marks.

• 6063 (architectural alloy) → Very common in window frames, door frames, pipes. Scrap often appears as hollow extrusions, shiny silver surface, lightweight and elongated shapes.

• 5005 (sheet alloy) → Used in roofing, cladding, decorative sheets. Scrap often comes in thin flat sheets, silvery but can be weathered or painted.

• 3000 series (like 3003) → Manganese-alloyed, softer. Common in roofing sheets, siding, beverage cans. Scrap often looks like thin corrugated sheets or used cans.

ADC12

ADC12 is a highly versatile secondary aluminum alloy, valued for its excellent castability, moderate strength, and cost-effectiveness due to its recycled content. Its widespread use in automotive, electronics, and industrial applications underscores its reliability and adaptability. While it may not match the strength of some primary alloys or perform well in extreme conditions without coatings, its balance of properties makes it an outstanding choice for high-volume, precision die-casting projects. For detailed specifications or material selection guidance, consult resources like the JIS H 5302

A356

A356 is used in industries requiring high strength, corrosion resistance, and precision casting:

• Automotive: Alloy wheels, suspension components, engine blocks, cylinder heads, and transmission cases due to its strength, fatigue resistance, and lightweight properties.

• Aerospace: Structural components, housings, and fittings requiring high strength-to-weight ratio and corrosion resistance.

• Marine: Components exposed to saltwater, such as pump housings and propeller parts, due to excellent corrosion resistance.

• Industrial: Machinery frames, pump bodies, and valve components requiring precision and durability.

• Consumer Goods: Bicycle frames, sporting equipment

製程與技術

Process & Technology

At the Pinjaya plant, advanced HERTWICH automated melting systems enable a highly efficient, low-energy production process that consistently delivers ISO 14021-certified recycled aluminum meeting international standards.

製成

Scrap Preparation

Aluminum scrap is first cleaned, dried, and compacted to prepare it for the melting process.

Melting

The prepared scrap is then fed into furnaces (rotary, reverberatory, or electric induction) where it's melted into a liquid state.

Casting

The refined, molten aluminum alloy is then poured into molds to form ingots or other shapes, which can be further processed into sheets, extrusions, and other products.
