The Yeltz soon settled as inspirational captain Paul McCone headed on a James Bowen free-kick to earn a 9th minute corner and Ash Sammons struck a trademark long range drive wide from Robbie Bunn's free-kick a minute later. The visitors went close when Jordan Hulme played a clever flick for John Johnston after 12 minutes but the resulting corner was played straight into the arms of home goalkeeper Bradley Catlow.
The best first half chance came for the Yeltz after 20 minutes when Reece Hewitt won the ball in midfield and burst forward before unleashing a great 20 yard shot, only for the ball to bounce back off the post with leading goalscorer Montel Gibson firing the rebound high.
As Altrincham began to stretch the game, a 27th minute free-kick was lofted over the bar by Ashley Hemmings, a 34th minute corner was punched clear by Catlow and McCone then made a great 35th minute challenge for another Alty corner.
The Yeltz enjoyed a better spell just before the break with their neat interchanges of passes. Lively Luke Yates and Gibson linked up after 40 minutes but the final shot from Yates was headed away and Sammons forced a 44th minute good save from goalkeeper Anthony Thompson.
Catlow made a good save to beat the ball away from Simon Richman at the start of the second half and Thompson saved from Yates at the other end. As home confidence grew, Hewitt cut in to fire high in the 56th minute for Halesowen and Bowen played a great ball for Jamie Molyneux to earn a 58th minute corner.
But Alty looked dangerous as they played a series of low crosses along the Halesowen goal and Catlow smothered the ball from substitute Thomas Peers in front of goal after 64 minutes. McCone continued to dominate at the heart of the Yeltz defence and he did well to clear for a 68th minute corner.
The Robins finally broke both the deadlock and Halesowen hearts in the 72nd minute when the ball was played out for Hemmings in space on the right and he whipped in a low ball for substitute PEERS to slide in and convert from close range.
But Halesowen continued to play neat football and create chances in a proud team effort. A 76th long range, low 30 yard drive by Bunn was turned around his post by goalkeeper Thompson for a corner and the Yeltz went even closer still in the 78th minute when Yates met Bunn's free-kick only for his header to strike the far post with Thompson beaten.
Alty doubed their lead in the 82nd minute when a Hemmings corner was pushed away by Catlow, but JOHNSTON was on hand to slam home the loose ball from 15 yards. An 89th minute free-kick from Joshua Hancock was then turned around the post by Catlow.
Far from being down-hearted, the Yeltz created pressure with further neat football and were almost rewarded with a deserved goal in injury time when McCone headed across goal for substitute Jamie Lucas to miss from just three yards out.
