Specifies the maximum stress the material can withstand while being stretched before breaking.

However, it is not a tutorial; it is a specification sheet. If you do not have a background in metallurgy, the tables will be difficult to interpret. For the professional, it is a 5-star reference document. For the hobbyist, it is a confusing list of numbers. If you want to for this document, let me know: (e

GOST 2685-75 is a former Soviet national standard, titled in English as "Aluminum Casting Alloys: Grades, Technical Requirements, and Test Methods" . It was officially enacted by the on January 1, 1977 . The standard focused on aluminum alloys specifically designed for creating complex shaped castings (also known as фасонные отливки ). It classified alloys into various categories, including aluminum-silicon, aluminum-silicon-copper, aluminum-copper, and aluminum-magnesium systems, with each category containing specific grades (e.g., AL2, AL4, AL6, AL8).

Since GOST standards are official state documents from the USSR/Russia, they are widely archived. You can find them through the following methods: : However, it is not a tutorial; it is a specification sheet

Known for exceptional fluidity and low shrinkage during solidification. They are ideal for complex, thin-walled castings.
