Super-strong metal / alloy request

I need to construct a grip that will be 1mm thick, by 3mm wide, and which will have a length of 50mm. (The 1mm could possibly be increased to 1.5mm - but no more.)

At the very end of the "grip" the force needs to be about 10KG.

Minimal bending is fairly critical; cracking is simply out of the question.

So far, tungsten and titanium have cropped up as potential materials - but if anyone has a better recommendation, such as an alloy, all information would be appreciated.

It would also be useful to know if this metal / alloy could be brazed to something like brass or aluminium. (Aerospace grade Al.)

Thank you.

Titanium is light and heat-resistant, but you didn't name those as desirable qualities. Tungsten is at the other extreme with regard to weight.

Your demands sound similar to a material used for drill bits. Tool steel and tungsten carbide come to mind as possible candidates. Tool steel is much cheaper and easier to work.

Thanks, Mark.

Light and heat-resistant do not come into the equation - they are not an issue at all.

I am really looking for the strongest metal / alloy that will perform to my specifications.

Have you done any Strength of Materials calculations to tell you where common steel performs in regards to your wishes.

If the safety margins for yielding are about 3 or better and the deflection is OK, then you can consider both lower stiffness and lower strength materials, or thinner thickness of steel (and naturally you can consider ranking various steels easily because they all have about the same elastic modulus, but varying yield strengths).

You know, mentioning tungsten and titanium throws people off, as if there are some reasons why these materials might be appropriate, but you have neglected to explain.

Then, tossing in brazing as a "useful to know" feature begins to put interesting icing on the cake.

This sounds disorganized, or as if it is just too much trouble to think rationally about.

Have you had to specify a material for an application before?

----------------------------- please note if it is a one task job or a multi task job it might make a difference for instance if it is a screw to drive (with say an hexagonal head) the geometry of the tool might give a solution because if for instance you use a closed 'ring' tool it needs much less strength of the involving materials because geometrically the ring gives maximum efficiency IE more than an open wrench the ordinary tools i know are chrome vanadium steel in general it makers a difference if the maximum needed strength is tension of compression (torsion is a sub case of the above) and generally tension design is different from compression design so you have to be more specific to get the needed maximum efficiency strength
