Heat-treated steel is steel that has been heated and cooled in a specific way to change its internal structure. It works by changing the microstructure of steel, which is made up of grains that form during solidification and cooling. The goal is to control how these grains form and change.

Chrome is a metal coating that gives a shiny finish and protects against rust. Stainless steel is a solid metal mix that naturally resists corrosion and stains. Chrome looks bright and smooth, but it is just a thin layer on top of another metal. Stainless steel is tough all the way through and does not need extra coating. Both have unique uses and benefits, but their properties and costs differ.

So yes, aluminum is ductile, especially in its pure form. However, the level of ductility changes depending on the alloy and how it’s processed.

More and more industries are using titanium, changing how buyers view pricing. The cost of titanium per pound isn’t always clear. It can change due

The number 316 refers to the grade in the 300 series of stainless steels. It’s austenitic, meaning it has a face-centered cubic crystal structure. It contains iron, chromium, nickel, and molybdenum, which give the metal its strength and rust resistance.

Tin is not a magnetic metal. Standard tin does not react to magnets, and you cannot attract it with a magnet. Tin is known as a “diamagnetic” material, which means it creates a weak opposing force to a magnetic field.

201 stainless steel is part of the 200 series of austenitic stainless steels. It contains less nickel than 304 but adds more manganese and nitrogen to compensate. This change helps lower the cost while keeping much of the needed strength and ductility. The standard composition includes around 16–18% chromium, 3.5–5.5% manganese, 4–6% nickel, and small amounts of nitrogen and carbon.

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.
