Slip Rings

Copper alloy slip rings

Copper alloy rings — tin/phosphor bronze, brass and beryllium-copper rings for slip-ring assemblies (≥200 A class), high-speed motor commutators and alternators. High wear resistance & conductivity; verify alloy, size and duty.

Application	Copper alloy rings for electrical machines — slip-ring assemblies (industrial high-current motors: wind turbines, cranes, rotary tables; ≥200 A class), high-speed motor commutators (phosphor bronze), alternator slip rings, brush gear collectors.m.highvolt

Compatible Models

Slip-ring motors — wind turbines / cranes / rotary tables (8-ring three-phase class) — verify High-speed motor commutators (phosphor bronze class) — verify Alternator slip rings (Delco AD230/LR630-class Ø14.7 mm) — verify Marine motor slip rings (tin/phosphor bronze 0–240 V) — verify **Always verify**: ring OD/ID

Description

Overview

Copper alloy rings — precision rings for electrical machines, supplied in tin bronze, phosphor bronze, brass and beryllium copper to match duty: slip-ring assemblies for industrial high-current motors (wind turbines, cranes, rotary tables), high-speed motor commutators and alternator slip rings.m.highvoltage-motor.com

Alloy Selection

Tin / phosphor bronze: high wear resistance + excellent conductivity
Phosphor bronze (90–95% Cu / 3–8% Sn / 0.1–0.3% P): high-speed commutators — near-pure-copper conduction, harder & wear-resistant
Beryllium copper: mechanical + electrical/thermal strength, explosion-proof slip rings
Brass (Zn<35%): general duty, good electrical performance & wear resistance
