Trombones commonly contain copper, since they are typically made from brass. Brass is an alloy, made of copper and zinc - mostly copper. Most all trombones plated in nickel, black nickel, silver or gold are still brass underneath. FYI: "Gold brass" is an uninformed way of referring to yellow brass, a common alloy composition of 67% copper and 33% zinc, and is not actually gold. Additionally, some trombone bells have a red color. This just means that there is more copper in the brass composition, more like 85% copper, 15% zinc. This redder color is often referred to as "Rose Brass" or "Red Brass". Although, true red brass is not brass, but what is known as gunmetal, an alloy that contains copper, zinc, tin & lead. BTW: Bronze and brass are similar, as they both contain copper. However, bronze is an alloy of copper and tin, instead of copper and zinc.

They are real but they aren't actually Limited Edition nikes. On nike iD you could make the gunmetal nike dunks but not anymore. Nike took the metallic leather option off so the closest you can get to the gunmetal dunks is the not shiny full grain leather. :/
Gunmetal-gray is considered a dark color. It is a shade of gray that has a slightly metallic finish, giving it a darker and cooler tone.
Gunmetal has a density of about 8.8 grams per cubic centimeter. We say "about" because gunmetal is a type of bronze (which is sometimes called red brass in the U.S.) and is an alloy of a lot of copper and some zinc, tin and lead. But the percentages of the metals used in the alloy can vary just a bit. Commercially pure gunmetal is usually considered to be composed of 85% Cu, 5% Zn, 5% Sn and 5% Pb. And 8.8 grams per cm3 is about right on the money.
