Tungsten is often brittle and hard to work in its raw state; however, if pure, it can be cut with a hacksaw. Tungsten is also the only metal from the third transition series that is known to occur in biomolecules. In its raw form, tungsten is a steel-gray metal that is often brittle and hard to work. But, if pure, it can be worked easily.

Reusing Old Hard Drive Magnets : 5 Steps (with Pictures

The magnets are great because they are very strong Neodymium that will hold anything firmly in place. These magnets are usually mounted to some sort of metal bracket with holes which will help you mount them and gives strength to the brittle magnets. To take apart hard drives you need a few small Torx drivers, usually T6, T7 and T8.

Why is cast iron brittle and why does it crack easily

Cast iron has a high percentage of carbon. As it cools from the molten state, graphite crystallizes out of solution at the grain boundaries to give a granular structure that has low tensile strength and shatters easily. Cast iron has good compress

Ring Guide: Which Type of Metal is Right for You? | BridalGuide

Tungsten rings are popular among men for the gray metal look, affordable price, designer style, and durability. They're dense, scratch-proof, and require little maintenance. Tungsten carbide rings can also be plated in gold or black. One caveat: Being a very hard metal makes tungsten brittle — i t can shatter on high impact.

Failure Modes: A Closer Look at Ductile and Brittle Overload

The metal deforms plastically before finally breaking. Sudden impact frequently causes a ductile material to behave in a brittle manner. There is not enough time for microscopic movements to take place. Brittle behavior is often seen in a catastrophic failure when the overload is very sudden. Stress Concentrations

Meteorite Identification - The Meteorite Exchange, Inc

Metallic iron in rocks from the Earth is very rare. The moist atmosphere of the Earth has turned almost all native iron to some other chemical form of iron long ago. So, if you grind off a small spot on your suspect rock and find bright shiny metal spots this is another good indication that you might have a meteorite of the stone type.
