Aluminium Pure

Durable, sustainable, energy saving

Alu­minium Pure proves how good sus­tain­abil­ity can look. Thanks to the nat­u­ral­ness of the largely un­treated surface, Alu­minium Pure blends in par­tic­u­larly well with exposed con­crete walls and natural wood. Com­pared to an an­odised surface, 37% less energy is con­sumed during pro­duc­tion.

Alu­minium shines with many pos­i­tive prop­er­ties in terms of pro­cess­ing, use and, above all, re­cy­cling. The ma­te­r­ial can be re­cy­cled again and again without loss. It is very pleas­ant to the touch - above all because this light­weight metal adapts par­tic­u­larly well to the ambient tem­per­a­ture. FSB only uses alu­minium for its hard­ware for doors and windows with a foot­print of 4 kg CO₂/kg - a quarter of the global average.

The new Alu­minium Pure surface with its unique mul­ti­fac­eted ap­pear­ance is a symbol of sus­tain­abil­ity, as the last three steps of con­ven­tional alu­minium pro­cess­ing are elim­i­nated.

No fine dust is created by pol­ish­ing or blast­ing, nor is the fitting an­odised. This saves water and elec­tric­ity and fa­cil­i­tates re­cy­cling at the end of the life cycle. Com­pared to the natural an­odised alu­minium surface, a further 37 % of energy is saved.

Alu­minium Pure proves how good sus­tain­abil­ity can look. The unique look results from the un­con­cealed nat­u­ral­ness of a largely un­treated surface. The matt and almost "raw" ap­pear­ance has a dif­fer­ent effect de­pend­ing on the am­bi­ence and in­te­rior concept. For example, Alu­minium Pure blends in par­tic­u­larly har­mo­niously with exposed con­crete walls and natural wood.

Over the years, handles made of alu­minium Pure gain in ra­di­ance and charm: as the surface is not pro­tected by an an­odised layer, it changes over time in the areas that have been touched. Ar­chi­tects already know and ap­pre­ci­ate this "patina of use" on FSB bronze prod­ucts.

FSB offers three product col­lec­tions in the Pure alu­minium finish - in­clud­ing the FSB 1289, FSB 1292 and FSB 1267 designs, the latter of which pays homage to the lever handle designs by ar­chi­tect and Bauhaus di­rec­tor Ludwig Mies van der Rohe.

Made for hands and with passion

Our quality as­pi­ra­tions are ex­em­pli­fied by a process that has been per­fected over decades, in which prod­ucts are cast in alu­minium at a tem­per­a­ture of 660 degrees Celsius. The molten alloy is poured di­rectly from a ladle into the die. The alu­minium fills the cavity and is shaped ex­clu­sively under the force of gravity.

After cooling, the casting is in­spected for quality and the sprue is removed for re­cy­cling. The blank is then sanded by hand and for­warded for its final surface treat­ments. Vi­bra­tory fin­ish­ing of the blanks in drums typ­i­fies the ex­ac­ti­tude for which FSB is known.

The edges and corners are gently de­burred and bright­ened by rubbing against small ceramic cones. De­pend­ing on the client’s wishes, the surface is finally pol­ished or blasted and, for colour fin­ishes, either an­odised or pow­der-coated.

Projects

Bauhaus-Mu­seum, Weimar

The Alu­minium Pure surface is already in use at the Bauhaus Museum in Weimar. It blends har­mo­niously into the work­shop and in­dus­trial char­ac­ter of the build­ing. To­gether with FSB, ar­chi­tect Heike Hanada de­vel­oped a special version of the FSB 1147 lever handle to match the pro­por­tions of the museum doors.
