5754 aluminum is an aluminum-magnesium alloy. It contains around 3% magnesium, which helps boost its strength and resistance to corrosion. This alloy is non-heat-treatable, so it gets stronger through cold working, not heating.

Graphite doesn’t have one fixed density. It changes depending on the type, purity, and production method. Understanding these differences helps you select the right graphite for your use.

Graphite density usually falls between 1.5 and 2.26 grams per cubic centimeter.

At room temperature (around 20°C or 68°F), tungsten has a standard density of 19.25 grams per cubic centimeter (g/cm³).

This makes tungsten nearly twice as dense as lead and almost four times as dense as aluminum. It remains stable at most working temperatures, meaning its density does not change significantly in typical environments.

No, gold does not rust. Gold is a noble metal. That means it resists reacting with air, water, and most chemicals. So, pure gold doesn’t form rust, corrosion, or tarnish in regular conditions. However, gold alloys can behave differently depending on the metals with which they are mixed.

Pure brass shows no attraction to magnets. This is because its main ingredients—copper and zinc—are both non-magnetic. When combined, these metals do not create any strong magnetic field.

You can hold a strong magnet next to a clean piece of brass, and it won’t move.

Copper is not magnetic. You can place a copper wire or pipe next to a magnet, and nothing will happen. It won’t stick, and it won’t move.

This is because copper doesn’t have the kind of atomic structure that supports magnetism. Its electrons do not line up to create a magnetic field. So, unlike iron or steel, copper shows no attraction to magnets in normal conditions.

Many people confuse rust with corrosion. Rust is a specific type of corrosion that affects iron and steel. Aluminum does not rust because it contains no iron. But that doesn’t mean it stays untouched by its environment.

Nickel doesn’t “rust” in the traditional sense, but it can corrode. Rust, by definition, is the reddish-brown iron oxide that forms when iron reacts with oxygen and water. Since nickel doesn’t contain iron, it doesn’t produce this type of rust.

Zinc doesn’t rust in the same way that iron does. It doesn’t form the flaky, reddish-brown layer we usually associate with rust. Instead, zinc reacts with air and moisture to form a thin surface layer. This layer doesn’t damage the metal—it protects it.

But under certain conditions, zinc can still corrode over time. The way it reacts depends on the environment and the type of zinc coating used.

Pure aluminum has a density of 2.7 grams per cubic centimeter. This value remains nearly the same across all common grades, unless alloys or extreme conditions alter it. The number tells you how much one cubic centimeter of aluminum weighs.

Aluminum is a silver-colored metal. It is soft, lightweight, and has good corrosion resistance. Pure aluminum is rarely used for parts. It’s too weak for most load-bearing tasks. But it’s excellent for electrical wiring and chemical equipment because it resists corrosion and conducts electricity well.

Low alloy steel is a type of steel that has small amounts of added elements, usually between 1% and 8%. These elements are added to improve the steel’s strength, hardness, resistance to rust, and toughness. Common added elements include chromium, nickel, molybdenum, and vanadium. These make the steel stronger and more durable than regular carbon steel but without the high cost of stainless steel.

Both 6061-T6 and 6061-T651 offer high strength, good corrosion resistance, and excellent machinability. The main difference is stress relief. T651 is stretched after heat treatment, which reduces internal stresses. T6 is not. For most projects, either option can work, but T651 provides more stability when tight tolerances or large plates are required.

18/8 stainless steel is an alloy mainly made of iron, chromium, and nickel. Chromium provides rust resistance, while nickel helps maintain the metal’s stability and shine. The typical blend is 18% chromium and 8% nickel, balanced with iron and tiny amounts of other elements. These different elements might include carbon and manganese to add strength.

310 stainless steel is an austenitic stainless steel. It belongs to the 300 series, known for its corrosion resistance and good strength. Among them, 310 offers better high-temperature strength than types 304 or 316.

This alloy is designed to work in heat-intensive applications. It stays stable and resists scaling even when exposed to temperatures above 1000°F. That makes it a reliable choice for heat exchangers, furnaces, and thermal processing equipment.
