Titanium Castings

Cti has an ability to supply fully certified Titanium castings to users around the world that is un-rivalled in the UK.

Our capabilities have been developed to support casting statically or centrifugally using graphite or investment casting moulding techniques.

They include extensive knowledge of design and simulation for manufacture, using both the Magmasoft® and ProCast® software packages.

We can make components using either investment casting techniques based on traditional wax tooling or our range of prototyping technologies, which are particularly suited to one off and low volume components.

Applications

Cti has wide ranging experience of making Titanium castings for the chemical, oil and gas and marine sectors, where the metal and its alloys are used for their corrosion resistance.

We have also supplied the aerospace and defence sectors, where the high strength to weigh ratio is a key attraction, making small blades and components for aircraft refuelling probes and parts for the European Joint Strike Fighter and the M777 Howitzer.

We have also supplied the automotive sector with Titanium turbines for turbocharger and components for exhaust systems for high performance cars, the medical sector with small implants and the safety sector with sprinkler nozzles for fire extinguisher systems installed in corrosive atmospheres.

Looking to the future, we are increasing our capacity so that we will be able to produce large scale Titanium components, up to and including aero engine casings.

Facilities

Our first Titanium furnace was, commissioned in 2001 and is capable of melting up to 30kg of metal.

We later added a second furnace capable of melting up to 90kg, using the same Induction Skull Melting (ISM) process and recently unveiled plans for a £15 million investment in a Vacuum Arc Remelting (VAR) furnace.

That furnace will be capable of producing castings weighing from 150kg to 1000kg and will be one of the biggest in Europe, for producing Titanium aerospace components.

The new furnace will give us the capacity to pour from 12kg to 1000kg of molten Titanium and its alloys into moulds ranging in size up to a maximum of 2.5 metres in diameter and 2.5 metres high.

Our melting and casting facilities are supported by a finishing shop, inspection department and metallurgical services, with the capability to conduct post cast processes, including vacuum heat treatment, and fully certify the castings produced.

Quality

Cti’s Quality Management System is certified to AS9100C (EN 9100:2009), which means we can make castings that meet aerospace standards.

We are approved to the NORSOK M-650 Rev 4 standard, established by the Norwegian petroleum industry and can supply commercially pure titanium alloy castings in accordance with NORSOK MDS-T02 Rev5.

We also hold several accreditations from Nadcap, the global accreditation programme for aerospace, defence and related industries, including accreditations for Vacuum Heat Treatment (AC7102), Welding (AC7110) and Dye Penetrant and X-Ray Inspection (AC7114/1and AC7114/4).

Materials

Cti has long experience of manufacturing certified castings in commercially pure Titanium (ASTM B367 C-2) and its common alloy, 6Al-4V (ASTM B367 C-5) to make both volume product and single or low volume prototypes.

We also have experience of making prototypes and development castings from other reactive alloys, including include Ti-1.5Al, TiXT, Ti 6-2-4-2, Ti 6-2-4-6, Ti 10-2-4, Nitinol, Gamma Titanium Aluminide and Zirconium alloys.
