Material Composition

Sterling silver lip plate and riser, Britannia silver head joint, body and foot joint, silver mechanism - drawn tone holesA traditionally created silver alloy composed of 95.8% silver, also dubbed the Britannia Silver for its historic existence in British coinage. This alloy has an increased density and is considerably softer than Sterling Silver. This allows the instruments to make darker and richer tonal color without the use of greater wall thickness.

The process to create the sintered 99.7% silver key pipes is unique to Altus. Powdered silver metal is compacted at a high temperature to fuse particles together directly into a rigid tube, strengthening our key pipe structure and increasing playability.

This model comes with two other options for tubing: medium heavy and heavy wall.

• Silver
• Open hole
• Offset
• E-mechanism
• Low B
