Unlike Gucci T shirts there are standardized numbers for the various aluminum alloys
used in industry, but bike companies like trade names ,

so have a sticker without that ... because stickers are a thing to add.

so 7075-T6 is a specific material. inticating % of elements in it's composition
the T number is a treatment.
