Why
Choose Titanium?
Titanium
is the fourth most abundant structural metal in the earth's
crust and is the ninth industrial metal. No other engineering metal
has risen so swiftly to pre-eminence in critical and demanding
applications. We at HEL Performance are always looking to strengthen
our range of world leading products and again have been the first to
see the benefits and performance offered to the customer by
Titanium. It has meant that for light weight applications you no
longer have to use the dangerous aluminium fittings on brake lines.
It means that you now have the choice of sharing another world first
with HEL Performance. It now means that you can be ahead of the game
- have a material unavailable from any other manufacturer for such a
wide range of brake line kits. It means now a select group of riders
can show they are true performance junkies - wanting the highest
quality, lightest materials but with the strength and performance to
say you really are serious about performance. Born on the race
track.....

Applications Of Titanium
Titanium
and its alloys have proven to be technically
superior and cost-effective in a wide variety of aerospace,
industrial, marine and commercial applications. For example :
In
the majority of these and other engineering applications Titaniumhas
replaced heavier, less serviceable or less cost effective materials.
Designing with Titaniumtaking all factors into account has
resulted in reliable, economic, and more durable systems and
components, which in many situations have substantially exceeded
performance and service life expectations.
Increasing
demand for more fuel-efficient and environmentally friendly road
vehicles has focused interest on weight reduction and improved
performance. Automotive applications of titanium follow logically
from the high strength, low density and, in select applications, low
modulus of titanium alloys, and their excellent resistance to
corrosion and oxidation. Titanium has a long record of
success in performance and racing applications. Applications

Reducing
the weight of vehicles, private vehicles in particular, is just one
aspect of the complex challenge which today's designers are facing.
Making motorcycles smaller, an apparently obvious strategy, creates
problems in providing acceptable free space. Small, lighter weight
motorcycles are unlikely to satisfy the aspirations of every rider.
Weight reduction in the top class of motorcycle, - contributes to
the reduction of fuel consumption, and the 'green' image of the
manufacturer. Cost represents a particular challenge for
fundamentally more expensive materials such as titanium. A recent
check in the US and Europe suggests the following levels of cost are
affordable for weight saving.

Design Concepts
Overall, a vehicle weight reduction of 1% is claimed to give a
reduction in fuel consumption of some 0.7%. Weight reduction in the
moving parts of the engine is however likely to be much more
effective in achieving improved fuel economy than body weight
reduction. Titanium alloy density is some 60% that of steel,
and the elastic modulus is about half that of steel. Direct
substitution of steel parts with Titanium in practice should
produce an immediate weight reduction of at least 40%. The low
modulus of titanium is beneficial for springs, but component
redesign may be necessary in stiffness limited applications.
Specific strength, and likewise specific toughness and fatigue
limits of Titanium compare very favourably to both steel and
aluminium alloys.
