Client NewsTirupati Graphite plc: Development of Ground-Breaking Graphene-Aluminium Composite
Tirupati Graphite plc, the fully integrated, revenue generating, specialist graphite producer and graphene and advanced materials developer, is pleased to announce that Tirupati Graphene and Mintech Research Centre (‘TGMRC’), its graphene and technology development unit, has developed a ground-breaking graphene-aluminium composite (the ‘Al-Gr Composite’ or the ‘Composite’), which exhibits significantly higher conductivity and strength properties over aluminium and comparable to copper. The Company has now engaged with potential end users including a FTSE 100 company for its potential use replacing copper in thermal, power and propulsion systems, which provides significant advantages owing to reduced weight.
The Al-Gr Composite successfully combines graphene with aluminium resulting in enhanced thermal and electrical conductivity and improved mechanical properties retaining aluminium’s light weight:
· Micro-hardness increased >300% over aluminium, which is 50% higher than copper
· Thermal conductivity increased to >200% over aluminium, which is better than copper values
· Electrical conductivity increased to >150% over aluminium, which is >95% that of copper; the Company aims to increase this with further optimisation
· The composite is almost free from oxidation and carbide forms of aluminium, a critical achievement breaking the key technological barrier in development of the Composite
