3.4 ounces (100ml) or smaller container. Aha! So technically, you can actually carry more than 3 ounces! This is good news for folks who travel with toiletries from most of the rest of the world, which uses a metric measurement system, and whose toiletry bottles are often 100 milliliters in size.
Uses: Manganese is an important alloying agent. It is added to improve the strength, toughness, stiffness, hardness, wear resistance, and hardenability of steels. Together with aluminum and antimony, especially in the presence of copper, it forms highly ferromagnetic alloys.ses: Manganese is an important alloying agent.

Less than 10 percent of all the manganese used in the United States goes to the production of manganese compounds. Perhaps the most important commercial use of these compounds is manganese dioxide (MnO 2 ). Manganese dioxide is used to make dry-cell batteries.
