Type 304 stainless steel is the most commonly used grade of foil. It is strong, resists corrosion, and is often used for food and beverage, machinery, aerospace, chemical, and cryogenic applications.

Type 309 stainless steel foil conducts heat and is often used in high-temperature environments. This foil is easy to work, resists corrosion, and is typically used for thermal, ornamental, and electrical applications.

Ultra-high temperature 321 stainless steel foil is made with titanium to provide extra resistance to high temperatures, corrosion, and cracking. This alloy is often used for electrical, ornamental, and thermal applications. Type 321 stainless steel is also called a ticronic material.
