Aluminium Alloy Ingots
LM6 Aluminium Alloy Ingot
LM6 is an aluminium-silicon casting alloy known for excellent fluidity, ductility and corrosion resistance. MET ASIA Alloys reviews LM6 requirements against relevant producer capabilities within our network, with chemistry and certification confirmed on a transaction-specific basis.
Overview
What is LM6?
LM6 is a British Standard designation (BS 1490) for an aluminium alloy containing approximately 10 to 13 percent silicon with low copper content. The high silicon level gives the alloy excellent flow characteristics, making it suitable for intricate and thin-section castings.
Because copper content is kept low, LM6 offers good corrosion resistance and is frequently selected for marine, cookware and general sand or gravity die casting applications. Closely comparable alloys exist under other standards, so buyers should state the chemistry they require.
Typical characteristics
- Excellent fluidity for intricate and thin-section castings
- Good corrosion resistance, including in marine environments
- Good ductility and weldability relative to higher copper alloys
- Suitable for sand casting, gravity die casting and pressure die casting
Typical applications
- Cookware and kitchenware castings
- Marine fittings and components exposed to moisture
- Thin-section and intricate general engineering castings
- Pump, valve and water-contact components

Questions
LM6 — frequently asked questions
What is LM6 aluminium alloy?
LM6 is an aluminium-silicon casting alloy under BS 1490 with roughly 10 to 13 percent silicon and low copper. It provides excellent fluidity, good ductility and good corrosion resistance.
What are common LM6 applications?
LM6 is commonly used for cookware, marine fittings, water-contact components and intricate thin-section castings produced by sand casting or gravity die casting.
What chemistry and certification details should buyers confirm for LM6?
Buyers should confirm the silicon range, copper and iron limits, the referenced standard, the required test certificate format and any third-party inspection requirement before commercial confirmation.
Is LM6 the same as other aluminium-silicon alloys?
Several standards define closely comparable aluminium-silicon alloys. They are not automatically interchangeable, so the required chemistry should be stated rather than relying on the designation alone.
