LM24 Aluminium Alloy Ingot

LM24 is an aluminium-silicon-copper pressure die casting alloy under BS 1490, widely used for general engineering and automotive castings. MET ASIA Alloys reviews LM24 requirements against relevant producer capabilities, with chemistry and documentation confirmed per transaction.

Overview

What is LM24?

LM24 is a British Standard aluminium die casting alloy containing silicon with a copper addition. The combination gives good castability with higher strength and hardness than low-copper aluminium-silicon alloys, which suits general purpose pressure die castings.

LM24 is frequently produced from secondary aluminium feedstock and is commercially close to several other die casting alloys. Confirming the required chemistry range remains essential for critical applications.

Typical characteristics

  • Good castability for pressure die casting
  • Higher strength and hardness than low-copper Al-Si alloys
  • Good machinability for finished component production
  • Commonly produced through secondary aluminium routes

Typical applications

  • General purpose pressure die castings
  • Automotive and commercial vehicle components
  • Machine housings, covers and structural brackets
  • Consumer durables and hardware components

Industries served

LM24 requirements typically originate from the following industrial buyer segments.

Specification information buyers should provide

Accurate requirement definition allows a faster and more reliable capability review. When enquiring about LM24, please provide:

  • Required chemistry range and permitted impurity limits
  • Standard referenced (for example BS 1490 LM24) or internal specification
  • Ingot form, packing and quantity per shipment
  • Delivery country, destination port and Incoterm
  • Test certificate, inspection and documentation requirements

Questions

LM24 — frequently asked questions

What is LM24 aluminium alloy?

LM24 is an aluminium-silicon-copper pressure die casting alloy defined under BS 1490. It offers good castability with higher strength and hardness than low-copper aluminium-silicon alloys.

Where is LM24 typically used?

LM24 is used for general purpose pressure die castings including automotive components, machine housings, covers, brackets and consumer durable parts.

How does LM24 differ from LM6?

LM24 contains a copper addition that raises strength, hardness and machinability, while LM6 is a low-copper aluminium-silicon alloy chosen for fluidity, ductility and corrosion resistance.

What should a buyer confirm before ordering LM24?

Confirm the chemistry range and impurity limits, referenced standard, ingot form and packing, quantity, destination, Incoterm, delivery period and required certification or inspection.
