Description
FIELD OF THE INVENTION
[0001] The present invention relates to a material that is light in
weight and has good strength and can be extruded to be desired
shape.
BACKGROUND OF THE INVENTION
[0002] A conventional bicycle frame generally is made by steel,
aluminum alloy, carbon fiber composite material or even titanium
alloy. Nevertheless, some of the material such as titanium alloy is
expensive and is difficult to be machined so that only some parts
of the bicycle employ the titanium alloy. Carbon fiber composite
material needs a lot of complicated processes to form a desired
shape and it is also expensive. Manufacturers still develop
different alloys that can be used to conveniently make bicycle
frames, and more particularly, the new material should be easily to
be extruded and machined while still has good strength.
[0003] The present invention intends to provide a new developed
material that can be extruded and allows other elements to be added
to involve desired physical features.
SUMMARY OF THE INVENTION
[0004] In accordance with one aspect of the present invention,
there is provided a new material that includes 94% of Aluminum,
0.01 to 0.19% of Scandium, and addition alloys which can be
Magnesium alloy, Manganese alloy, Silicon alloy, Copper alloy or
Nickel alloy.
[0005] The primary object of the present invention is to provide a
material that can be extruded to be desired shapes of solid or
hollow tube and includes 94% of Aluminum, 0.01 to 0.19% of
Scandium, and addition alloys which can be Magnesium alloy,
Manganese alloy, Silicon alloy, Copper alloy or Nickel alloy.
[0006] The present invention will become more obvious from the
following description when taken in connection with the
accompanying drawings which show, for purposes of illustration
only, a preferred embodiment in accordance with the present
invention.
BRIEF DESCRIPTION OF THE ATTACHED CHART
[0007] Chart 1 shows the comparison between variety of aluminum
alloys and the material of the present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0008] The new material of the present invention comprises at least
94% of Aluminum, 0.01 to 0.19% of Scandium, and addition alloys
which can be Magnesium alloy, Manganese alloy, Silicon alloy,
Copper alloy or Nickel alloy. The Magnesium alloy, the Manganese
alloy, or the Silicon alloy makes the material to have better
structural strength. Copper alloy may make the material to be light
in weight so that the material can be used to make parts of
airplanes.
[0009] Besides, the Copper and Nickel alloy makes the material to
have a feature that bear high temperature. Also, the Silicon alloy
has the same function as the Copper and Nickel alloy.
[0010] In order to allow the material to be suitable for being
extruded, the new material of the present invention comprises at
least 94% of Aluminum, 0.01 to 0.19% of Scandium, and 5% of Zinc
which is helpful when the material is to be extruded to be solid or
hollow tubes.
[0011] Chart 1 shows the comparison between variety of aluminum
alloys and the material of the present invention. In the chart, the
material of the present invention involves several improvements in
the listed items when compared with the aluminum alloys.
[0012] While we have shown and described the embodiment in
accordance with the present invention, it should be clear to those
skilled in the art that further embodiments may be made without
departing from the scope of the present invention.
