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.

1 Manganese is essential in the production of steel and iron and this makes up the most common use of this metal. 2  It improves the workability of the steel when it reaches high temperatures.3  Adding about 8-15% of manganese also increases the strength of the steel.
