World-wide equivalent to 380 die cast aluminum

Looking for world-wide equivalent standards and material for 380 aluminum for diecasting.

When one begins to investigate "equivalent" compositions and standards for alloys, it is necessary to have the original designation as precise as possible. Assuming that 380 means UNS A03800 (380.0 according to ASTM B85), then the equivalent grades are as follows:

EN AC-46500 according to EN 1706 (also called EN AC-Al Si9Cu3(Fe)(Zn)

AlSi8Cu3Fe according to ISO 3522

ADC10Z according to JIS H 5302

EN 1706 replaces the various national standards from Europe. Many companies still reference these standards, so here are some of the obsolete ones as well:

LM24 according to BS1490

A-S9U3Z according to NF

AlSi9Cu3 according to DIN 1725

Also note that EN 1706 has two grades very similar to EN AC-46500 that are cast in higher tonnage in Europe: EN AC-46000 [Al Si9Cu3(Fe)] and EN AC-46200 [AlSi8Cu3]. The most significant difference is that both of these grades allow a maximum of 1.2% Zn instead of 3.0%. There are other differences in the allowable content of Si, Fe, Mn, etc.

WE are using LM-24 in our plant.
our custmor is specifying EN AC-46000.
can I use LM-24 for this.

Thanks,

Dear Sir,
Please suggest an alternative for grade 'EN-1706' in LM series as we in India use LM.
Can I have the chemical composition for the same.
Can it be used for sand casting?
