CF-PEEK and CF-PPS: Carbon-Fiber Polymer Machining
CF-PEEK and CF-PPS: Engineering Polymers Reinforced with Carbon Fiber Carbon-fiber-reinforced PEEK (CF-PEEK) and carbon-fiber-reinforced PPS (CF-PPS) represent the high-performance tier of machinable engineering polymers. CF-PEEK, typically containing 30% short or continuous carbon fiber by weight, offers tensile strength exceeding 200 MPa, a service temperature of 250°C continuous, and inherent flame retardancy. CF-PPS, usually 40% glass …
Kovar and Invar 36: Glass-to-Metal Seal Component Tools
Kovar and Invar 36: Controlled-Expansion Alloys for Precision Sealing Kovar (ASTM F15, Fe-29Ni-17Co) and Invar 36 (ASTM B753, Fe-36Ni) are iron-nickel alloys engineered for exceptionally low coefficients of thermal expansion (CTE). Kovar’s CTE of approximately 5.1 × 10−⁶/°C matches borosilicate and alumina glass, making it the standard material for glass-to-metal seal (GTMS) feedthroughs, electronic package …

Tantalum and Niobium: Reactive Metal Tooling Guide
Tantalum and Niobium: Properties That Define the Machining Challenge Tantalum (Ta) and niobium (Nb) are refractory metals prized for their exceptional corrosion resistance, biocompatibility, and superconducting properties at cryogenic temperatures. Tantalum finds widespread use in chemical process equipment, surgical implants, and capacitor anodes. Niobium serves as a superalloy additive and is machined into superconducting RF …
Deep Hole Drilling with Indexable Inserts: BTA vs Gun Drill
Deep Hole Drilling with Indexable Inserts: BTA vs Gun Drill Deep hole drilling is defined as any hole where the depth-to-diameter ratio (L/D) exceeds 10:1. In modern CNC machining, deep holes are common in hydraulic manifolds, injection molds, gun barrels, aerospace structural components, and heat exchanger plates. Two primary methods dominate the industry: BTA (Boring …

Molybdenum TZM Machining: High-Temperature Alloy Strategy
Understanding TZM: The High-Temperature Molybdenum Alloy TZM (Titanium-Zirconium-Molybdenum) is a molybdenum-based superalloy containing approximately 0.5% titanium, 0.08% zirconium, and 0.02% carbon. This composition produces fine carbide dispersoids throughout the molybdenum matrix, dramatically improving recrystallization temperature, creep resistance, and high-temperature strength compared to pure molybdenum. TZM retains useful mechanical properties above 1,200°C, making it indispensable for …
