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.

Manganese is one of the most abundant metals in soils, where it occurs as oxides and hydroxides, and it cycles through its various oxidation states. Manganese occurs principally as pyrolusite (MnO 2), and to a lesser extent as rhodochrosite (MnCO 3). More than 25 million tonnes are mined every year, representing 5 million tons of the metal, and reserves are estimated to exeed 3 billion tonnes of the metal.
