High temperature brazing materials
Alloy Powders & PastesHigh temperature brazing, developed some 60 years ago, has become an essential tool used in the manufacture of components made from stainless steel and other high temperature materials, especially for complex or intricate designs with many joints. Our partner's at LSN Diffusion manufacturing and technical team members have been part of the continuous development in brazing filler metal chemistries and application technologies.
Surface Flow Technologies & LSN Diffusion offer the widest possible range of nickel based brazing filler metals, brazing pastes and aids. Small lot sizes of customized or experimental brazing filler metals can be supplied to aid in development projects. Larger production quantities are supplied on a spot or long-term contract basis.
A range of binders which are used to apply and fix the powdered brazing filler metal is available. The binders may be organic or water based and designed for manual, automatic, spray, stencilling and print based methods.

Atomized powder size distribution
LSN Diffusion processes atomized powder by a combination of air classification and sieving to produce the powder Particle Size Distribution (PSD) to suit the surfacing equipment or brazing application deployed by the customer.
In-line and final Quality Control checks use test sieves and laser diffraction analysis equipment to ensure strict conformance to specification.
LSN Diffusion offers a range of standard PSDs coded to indicate the suitable method of application and equipment.
