Everything you wanted to know about titanium

If steel and titanium are both equal in strength, then aluminum is half the strength. When you get into the 7000 series of aluminum they get to about two thirds the strength of titanium. A titanium bolt with that same 1000 pounds of force is going to stretch twice as much. Because of stretching it will still carry the load as long as you are within the elastic limit. CNC machines were coming along and people could take titanium bar and machine it and make a fastener by just purely machining it out of bar stock. The problem with that is if you want to make an aircraft quality fastener, it needs to be hot forged, meaning it needs a forged head to get the proper grain structure, followed by the proper heat treating and then you need to have a rolled thread. So the same moly paste that you'd put on your cam lobes. Look for one with a 40 percent moly content. The molybdenum gets ground into the surface and prevents any galling between the titanium and aluminum, or ti on titanium nut.Titanium screw(Most of titanium alloy screws are titanium Gr.5, Ti-6al4v) have high specific strength, tensile strength up to 100-140kgf/mm2, and density is only 60% of steel. MMO titanium anode that using titanium as substrate and high catalytic activity of platinum group metal oxide as the coating with good electrical conductivity, small output resistance and good formability without corrosion applied widely in seawater, fresh water and soil environments.Not only is standard-size grade 2 titanium pipe and tube available from inventory or quick production runs, larger sizes also can be produced by independent fabricators. Many of them also can design and produce complete piping systems, heat exchangers, and pressure vessels. This geographically diverse fabrication base has more than 25 years of engineering and design experience.When considering the design of a stud or Gr5 titanium bolt used for cyclically loaded fastener, it is important to consider both the fastener stiffness and the stiffness of the parts being clamped. Bicycle titanium bolt come closest to steel in terms of strength but Ti is 47% lighter.It’s lightweight. That low density we just talked about is what makes titanium studs lighter than those made with other metals.
