advantages and disadvantages to titanium?

Question

i need some advantages and disadvantages to titanium? e.g it has good impact strength
it is an expensive material

Answer 1

bad:
It is hard to machine.
It is next to impossible to "cast" (i.e. like cast iron or cast aluminum).
In some machined forms it is more brittle than steel, although it has a higher tensile strength.
It is very expensive.

good:
It has a very high melting point (temperature), and very high plastic point.

Answer 2

Advantages: strength to weight ratio better than steel- about half as dense but about 2/3 as strong.

It is corrosion resistant and need not be painted.

It is non toxic and bio-compatible- it is the primary material for implanted prostheses such as artificial joints.

It is compatible with carbon composites, unlike aluminum.

It is castable (using hot isostatic pressing- most aircraft engine hot section parts are titanium castings) and can be formed to very deep sections with superplastic forming (blown into a mold from sheet at high temperature).

Disadvantages-

it's really expensive. It's really hard to machine. It can cause corrosion in aluminum if adjacent with moisture.

Largest use of titanium today is as titanium dioxide- the primary pigment in white paint since lead oxide was banned. Also in high demand for cheap stainless steel, which is 1/2% titanium.

Answer 3

Pure titanium is typically not used in the industry. Titanium alloys are used - The most common titanium alloy is Ti-6Al-4V.

Titanium alloys are corrosion resistant, bio-compatible and they have high specific strength as compared to steel.

They are also costly and difficult to machine. But you can machine them with acceptable productivity under high pressure cooling and cryogenic cooling.

Answer 4

Good:
Strong for a given weight (generally it is almost as strong as steel and almost as light as aluminum)
Resists corrosion

Bad:
Difficult to work with (form)
Expensive and often hard to find

Answer 5

It is strong and light, it has a high melting point. It doesn't corrode (as it forms an oxide layer like aluminium).

It is expensive (not because it is rare but because it is hard to extract from its oxide).

Answer 6

It is also non-magnetic (both an advantage and disadvantage).

It has also been sought after for its attractiveness in jewelry and art (it has a iridescent blue sheen when polished)

Answer 7

Doesn't corrode GSCE chemiserty

Answer 8

Good: is very light.
Bad: hard to machine
