Granges is also exploring business opportunities for advanced aluminium materials for brazed
automotive heat exchangers in North America.
Titanium was brazed
to itself and to aluminum alloys by Al-based fillers using an oxyacetylene torch with flux [30, 33], in high-purity argon [10, 33], in vacuum [28-31, 34-36], and in air conditions: in fluxless process assisted by the ultrasonic vibration (USV) [37-39] or by additional pressure .
All specimens were brazed
in the positive structure location and in the structure direction 0[degrees].
The agreement is in line with the companya[euro](tm)s strategy to satisfy global demand for low pressure and high pressure brazed
aluminium heat exchangers, Chart Energy & Chemicalsa[euro](tm)s president Mike Durkin said.
To ensure the oxidation and corrosion resistance of brazed
joints, Ni- and also Ag-based filler metals are usually recommended.
Such a flame drastically reduces the oxidation inside the brazed
pipes and joining metals.
This new, smaller copper brazed
plate heat exchanger for oil cooling applications is another step in the launch of the next generation heat exchangers from ALFA LAVAL.
They produce brazed
joints with high strength at both room and elevated temperatures and also corrosion resistance.
Appearance of some spot welded respectively spot pressure brazed
samples with the new electrode is shown in figure 4.
Vannatta said she created the antiwar sculptures by three different methods: carved stone, forged and brazed
copper, and cast bronze.
Many radiator manufacturers are replacing conventional soldered copper-brass heat exchangers with the new brazed
copper-brass heat exchangers and, where performance criteria favors copper-brass, they are switching back to copper-brass from aluminum.
MAG Maintenance Technologies also formulated a multi-flute brazed
carbide finisher, dubbed the "Dreamcutter," that has proven to be successful on finish cuts on thin wall applications of 8" deep with weight-saving wall thicknesses of 0.060" thick.
Fabric cladding reportedly wears more uniformly and is less expensive because the brazed
coating comes out smoother than a conventional welded overlay, which requires substantial machining.
Consider the deep drilling system from Iscar Metals (Arlington, TX; www.iscarmetals.com), which is a modular system that uses brazed
and indexable threaded drilling heads with either single- or double-tube shanks.
