Question:

What does nonstandard pure aluminium ingot mean?

What does nonstandard pure aluminium ingot mean?

Answer:

That is, parallel ingot, standard aluminum ingot purity of 99.7%, non-standard is below this standard.
For direct casting, the casting is good in toughness but not in strength and poor in physical properties.
Pure aluminium ingot: Aluminum exists in the surface, in addition to iron (Fe) in ranking the second metal elements, since the electrolysis method was invented, human made from bauxite surface, refining of high purity (more than 99.7%) of aluminum, is pure aluminum ingot.
Non-standard pure aluminum ingot refers to parallel ingot, standard aluminum ingot purity is 99.7%, non-standard is below this standard aluminum ingot.
