Stainless steel 304 is better or space aluminum

Both are good.

1, stainless steel 304 is a high-quality stainless steel material with high strength, corrosion resistance, good processability and other advantages, is widely used in the manufacture of chemical equipment, food processing equipment, medical equipment, building decoration and other fields. Stainless steel 304 is relatively expensive, but has better durability and maintenance in the long run.

2, space aluminum is a lightweight, strong metal material with light weight, high strength, good thermal conductivity and other characteristics. It is widely used in aviation, aerospace and other fields, but also gradually used in automobiles, electronic products and other fields. The price of space aluminum is relatively high, but it has good durability and aesthetics.
