AI Guide

titanium barThe diameter and brand selection of titanium alloy rods determine their application adaptability in different scenarios.From Φ 3 mm thin rod medical fasteners to Φ 300 mm large specificationstitanium barThe high-end equipment spindle, accurate matching diameter and grade (such as TA2, TC4) is the key.Mastering these points will help scientific material selection, so that the light, high strength and corrosion resistance of titanium materials can play their due value.

I. WhyTitanium Barselection determines product success or failure

inChemical corrosion, marine engineering, medical equipment, aerospace, electroplating electrodes, precision machineryAnd other areas,titanium barWith titanium alloy rodsLight and high strength (density 4.51g/cm³, about 57.8% of steel), strong corrosion resistance (corrosion rate in seawater 0.01mm/year), good biocompatibilityThe unique advantages have become one of the core materials with more applications.

Many people are often selected.Different diameters, various grades, complex working conditionsThe combination of diameters makes it difficult to choose--in fact, as long as you master the rules of diameter classification, Understand the characteristics of common brands, Titanium rods and titanium alloy rods can be scientifically selected to meet their own needs.

Three elements of selection: working condition corrosion + mechanical strength requirements + processing molding requirements.Diameter determines bearing capacity, grade determines corrosion resistance and strength matching, and the best solution can be locked only when the two cross.

II. Classification by diameter: 4 categories adapt to different scene requirements

Combined with industry standards (GB/T 2965) and practical application scenarios, titanium rods and titanium alloy rods are usually divided into diameterThin stick, small stick, medium stick, big stickEach of the four categories has its own production process and application field, taking into account practicality and economy.

2.1 Fine rod (Φ3-10mm)

diameter interval: Φ3- 10mm, the finest can be Φ0.5mm (customized on demand)

manufacturing technique: precision cold drawing + multiple intermediate annealing, higher requirements for size accuracy and surface finish

core advantages: High size accuracy (tolerance ±0.05mm), smooth surface (Ra≤0.8μm), good flexibility

typical scenarioMedical fasteners (orthopedic screws, bone nail), electronic components, Aviation precision instrument component, Medical implant device accessories, Chemical precision valve stem

2.2 Small rod (Φ10-50mm)

diameter interval：Φ10-50mm

manufacturing techniqueHot rolling + fine grinding/turning, hot rolling + cold drawing combination process can be carried out as required

core advantages: Precision and cost-effective, cutting, turning, welding can be carried out according to demand

typical scenarioChemical equipment stirring shaft, valve stem, medical equipment parts, aviation standard parts, fastener blank, Electroplated titanium anode rod, Titanium welding wire base metal

2.3 Medium rod (Φ50-150mm)

manufacturing technique: Hot forging + finish turning, with heat treatment for some requirements

core advantages: Good strength and stability, can withstand large torque and impact load, and the tissue is dense.

typical scenarioChemical reaction kettle stirring spindle, ocean engineer connecting piece, Pressure vessel fittings, machining spindles, Marine propeller fittings, electrolytic cell titanium electrode

2.4 Big stick (Φ150-300mm and above)

diameter intervalΦ150-300mm, special requirements can be up to Φ500mm (multi-fire forging)

core advantages: High strength, good bearing capacity, impact resistance, uniform structure, stable mechanical properties

typical scenarioHigh-end equipment spindle, Deep-sea exploration equipment load-bearing elements, aeroengine component, nuclear power auxiliary equipment, Heavy machinery foundation, Main shaft of large ship propeller

Tips for process differences: Fine rod adopts precision cold drawing process, size tolerance is small;Medium rod and big rod adopt hot forging technology, and the internal structure is dense.When selecting the type, it should be combined with the processing method (turning/forging/welding).
