'As good as' is a silly phrase to use in metallurgy. Are we talking machinability, castability, tensile strength or hardness. Not to mention less obvious issues

'As good as' is a silly phrase to use in metallurgy. Are we talking machinability, castability, tensile strength or hardness. Not to mention less obvious issues like food safety or resistance to corrosion?
There are very many alloys of both aluminium and steel all of which have there uses. To say this one is as good as titanium means very little.

- maxerickson 12y agoThe linked abstract is somewhat clearer: http://www.nature.com/nature/journal/v518/n7537/full/nature14144.html http://www.nature.com/nature/journal/v518/n7537/full/nature1... The specific tensile strength and ductility of the developed steel improve on those of the lightest and strongest metallic materials known, titanium alloys So presumably it is stronger and somewhat more workable than titanium.
- dredmorbius 12y agoFrom TFA: "Dr Kim has produced a material which has the strength and the lightness of titanium alloys but will, when produced at scale, cost a tenth as much."

- chromaton 12y agoThen there's yield strength, ultimate strength, magnetic properties, heat/cold compatibility, toughness, ductility, density, weldability, modulus of elasticity and aesthetics.
- SapphireSun 12y agoDon't forget bioactivity / toxicity ;) Ti implants are popular because of the metal's low bioactivity amongst other desirable properties.
