An aluminium-silicon braze-cladding option listed by Gränges for controlled-atmosphere brazing of rolled heat-exchanger products.
Selected clad-layer chemistry only; no clad temper, standalone mechanical data or complete composition established.. Keep typical values, source minima and composition limits distinct. Reference records are not certificates or design allowables.

Fabrication and material selection
Treat this as a clad-layer material, with core alloy, layer ratio and brazing cycle specified separately. The brochure lists iron variants and permits zinc modification; this entry retains only the shared silicon interval.
Applications and product forms
Brazed heat exchangers
Standards and acceptance
Identify the governing product specification by the actual form and manufacturing route. A grade designation alone does not establish compliance or equivalence. Confirm the edition, required condition, inspection and dimensional limits through the supplier and an authorized specification.

Technical questions
Are typical values delivery limits?
No. A typical reference value describes the source condition; it is not a guaranteed minimum for a delivered lot.
Which temper and thickness should I compare?
Compare the same material form, temper, thickness/test condition, unit and value basis. Different conditions cannot be silently treated as interchangeable.
Technical sources and verification
Selected reference facts checked 14 October 2026. Source values apply to their stated material condition and are not certification of supplied stock.
