Foundry alloy of titanium ТЛ3 was developed by Association «Prometheus» for the Navy of the Soviet Union. This alloy belongs to the category of corrosion-resistant alloys. High quality allow it to be used in contact with sea water and an oxidizing atmosphere. The alloy produced in accordance with OST 5P.9071−88. The basis of it is titanium (up 85.2 — 91.5 per cent).

The percentage impurities of the brand ТЛ3

Alloy Technological quality Feature Use
ТЛ3 Good castability, good weldability. Low strength but good ductility and corrosion resistance. Details of marine engineering.

Titanium cast alloys c plate stricture have reduced characteristics of plasticity and strength of castings, low fatigue resistance and high fracture toughness.


Details of marine engineering, centrifuges, chemical reactors, crystallizers, distillers, dryers. Cast from titanium alloy to produce shell, cover pumps, plates, bushing, corner, safety valves, disks of ceramic valves, ball housings and impellers for centrifugal pumps.


To eliminate hidden marriage castings are hot isostatic pressing, which brings its structure to the structure of wrought iron. Is mandatory exterior inspection, check the chemical composition and mechanical qualities of castings. If necessary, conducted g-scopy, x-ray, ULTRASONIC flaw detection, fluorescent control, and testing under pneumatic or Hydrogenium.


On the website LLC «_" offers a wide range of products from titanium alloys. High quality products and the absence of middlemen determine the most advantageous offer for the acquisition of brand products ТЛ3 to solve the current production problems. Delivery in the shortest possible time in any region of the country and abroad, compliance with regulatory documentation already gained the trust of regular customers. Due to the high performance and wide model range of semi-finished products, brand ТЛ3 enjoys continued popularity in many spheres of production.
