Gunmetal, known as red brass in the United States, is a type of bronze, an alloy of 88% copper, 10% tin, and 2% zinc. Brass is an alloy of copper and zinc; the amounts of each can vary to create brass with various properties.
The biggest difference between bronze and brass is the density, mass, and weight. Bronze and brass are also made of different metals.
Brass is an alloy of copper and zinc, and it may contain very small amounts of other metals such as lead and tin. Red brass is an alloy which typically contains 85% copper, 5% tin, 5% lead, and 5% zinc.

Nickel is magnetic.
Most basically, brass is an alloy of copper and zinc, while aluminum is a pure element.
trombones have a slide but the rest of the brass are very similar but with likely keys or valves
Gunmetal - PC - was created in 1998.
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.
The main difference between woodwind and brass instruments is the material they are made of. Woodwind instruments are typically made of wood or metal and produce sound by vibrating a reed or blowing air through a mouthpiece. Brass instruments, on the other hand, are made of brass and produce sound by vibrating the player's lips against a mouthpiece.
Gumetal, or red brass, is a mixture of several metals which can be used in a variety of applications, from weaponry to technical equipment (vales and gears), to statues and even buttons.
The brass has much lighter color (yellowish to light reddish), then the copper (reddish brown). The brass is copper mixed with zinc. The more copper in the mix, the darker the color.
Red Brass is a Brass and Nugold is a Bronze! Brass is Copper alloyed with Zincwhereas Bronze is Copper alloyed with TIN. Red Brass is typically 85% Copper and 15% Zinc.Nugold is 90% Copper and 10% Tin. ~ the Silver Strumpet
