A titanium bar tolerance is not one number that applies to every diameter and finish. In one issued multi-size quotation, selected centerless-ground bars were quoted at ±0.0003 in, most centerless-ground items at ±0.0005 in, and one larger precision-ground item at ±0.002 in. Straightness was called out separately on selected diameters. Buyers should specify grade, standard, […]

How titanium weld color relates to shielding, oxygen and nitrogen pickup, heat tint acceptance, alpha case risk and titanium welding wire selection.

A high-temperature material selection guide comparing molybdenum and tungsten by melting point, density, machinability, standards and RFQ use cases.

A practical niobium vs tantalum selection guide for engineers and buyers comparing corrosion resistance, density, cost, ASTM standards and RFQ details.

Titanium’s corrosion resistance is a self-healing TiO2 oxide film, not the metal itself. How the passive film works, the three places it fails, and how Grade 7/12 fix them.

Grade tells you what the titanium is; condition tells you how it behaves. Annealed vs STA strength, surface finish and tolerance – what to actually put on a titanium bar PO.

A titanium part can pass its chemistry cert and still fail because of alpha case – a thin, brittle oxygen-enriched skin from hot work. What it is, why it matters, how to remove it.

Two real Ti-6Al-4V heats, side by side: the chemistry varies between melts but both are Grade 5. Why that happens, when it matters, and how to specify around it.

Oxygen, nitrogen, hydrogen and carbon decide titanium’s strength, toughness and grade at the ppm level. A practical read with real Ti-6Al-4V numbers and the oxygen-equivalent rule.

Titanium machining trouble is physics, not luck: heat trapped at the edge, adhesion to tooling, and a work-hardening loop. Here is why, and how the bar you start with changes it.
